Introduction to Tungsten Carbide Seat

Tungsten Carbide Seat Introduction: 
Tungsten carbide has properties of high hardness and good wear resistance. There is no obvious plastic deformation at room temperature. The products have good dimensional stability and high precision machining. WC-Ni based alloys have good chemical stability, acid and alkali corrosion, thereby increasing the life of the product. As the above-mentioned characteristics of the carbide, it is widely used in the ball rolling bearing industry body, fluid sealed rotary ball valve core, oil extraction machine one-way spool valve seat, and many other military and civilian high-tech fields.

The superiority of tungsten carbide ring

Tungsten carbide ring has the properties of high hardness, high compression strength and low friction coefficience.It has the advantages as follows:
1.high productivity
2.high wear resisitance
3.high accuracy and good surface condition
4.saving energy

The Application of Tungstne Carbide Ring

Tungsten carbide ring has been widely used in petroleum, chemical, textile, pharmaceutical, construction, metallurgy, food, printing and dyeing, paper, nuclear power, hydropower projects, city gas, aerospace, marine and other civilian and defense industry.

What's the differences between tungsten rings and tungsten carbide rings?

Some of manufacturers sell tungsten rings that do not include carbide. (Some of the retailers still call them tungsten carbide however, so be careful.) A tungsten only ring is basically a steel ring. It is very hard, but NOT scratch proof. A tungsten carbide ring can only be scratched by a diamond or a product containing the mineral corundum.

Hard Facts about Tungsten Carbide Rings

1. Tungsten carbide rings are the most wear resistant rings available on the planet.
2. Tungsten is about 10 times harder than gold, 5 times harder than tool steel, and 4 times harder than titanium.
3. Due to their extreme hardness, tungsten carbide rings will hold their shapes and shine longer than any ring on the market.
4. Carbide rings have been referred to as the "Permanently polished rings".
5. Carbide rings will NOT bend.

Introduction to tungsten carbide bearing

Tungsten carbide bearing is sintered by the process of combining the matrix and tungsten carbide powder together at high temperature.It is integrated by sintering after mechanical processing.Tungsten carbide bearing is characterized by strong abrasion resistance, erosion resistance and high hardness.Its life expectancy can be up to 300 hours.

Note of using tungsten carbide bearing

when using tungsten carbide bearing,we should pay attention to the tips as follows:

1.Be careful when processing.Serious cracks and fracture can lead to accidents.
2.Keep clean. Sweat of our hands will cause the bearings to rust,so it is best to wear gloves.
3.Using the right tool

The analysis of the tungsten carbide bearing wear

In general,tungsten carbide bearing can be allowed to reach the longest bearing service life if it is in proper use.But there will always be accidental damage. It is because of the careless installation of the bearing, the pay no attention to the intrusion of foreign bodies from the outside,etc.

The processing of tungsten carbide

With the refractory metal carbide(WC;TiC)as the main ingredient and Co,Ni, Mo as a binder, Tungsten carbide is pressed into the ring.It is sintered in vacuum furnace or hydrogen reduction furnace by powder metallurgy.

17th Century Fake Pearls and Strass Paste Gems

In the 1630s large quantities of pearls were used as clothing accessories.  To be truly fashionable pearls needed to be worn in abundance.  In the C17^th, Jaquin of Paris patented a method of making fake pearls.  He coated blown glass hollow balls with varnish mixed with iridescent ground fish scales.  The hollow balls were then filled with wax to strengthen them.  This method made Paris the main producer of fake pearls for over 200 years.

Paste is a compound of glass containing white lead oxide and potash.  Paste jewellery was usual in the 1670s and was worn at court.  The best and most long lasting paste jewellery was produced after 1734 by Georges Strass.  Most fake jewellery was Paris led. Just about any kind of fake gem could be made, including fake opals.  Many pieces of fake jewellery have survived in their original setting, but fine estate pieces of real gems were often broken up for resetting into more fashionable styles of the era. 

After 1760 the production of fake jewellery spread to London and to Birmingham.  Steel which was produced easily during the industrial revolution was used for settings for marcasite and jasper ware cameos.  Glass and Wedgwood porcelain paste cameos were made in English factories and were very popular too.

Ornate shoe buckles of paste, steel and tin were part of fashionable dress.  A similar fad at this time were elaborate paste jewelled buttons, fashionable in British society.  As well as fake jewellery gaining popularity, semi precious jewels such as uncut garnets became usual as part of less formal day dress.

Jewellery for the 21st Century

Costume jewellery can enliven a fashion wardrobe and bring a dash of panache especially for one off special occasions.  Costume jewellery can be superb.  The superb is usually plated at least seven times with 18 or 22 ct gold. 
For example Joan Rivers does a range of good costume jewellery modelled on original fine gem pieces.  One of her trademarks is to make jewellery doubly useful and she produces sets of interchangeable earrings, pendants and tennis bracelets.  For example you might be able to slip a range of up to 10 different coloured stones, pearls or Swarovski crystals into an 18^ct gold plated earring to vary the look.  Her jewellery is exclusive to the QVC shopping channel in the UK and she is constantly working on new ideas such is her enthusiasm.

Some of the costume jewellery I have come to love, comes from companies like Ciro, Adrian Buckley, Butler and Wilson, Swarovski Crystal Jewelry Napier, Joan Rivers, Joan Collins, Christian Dior, California Crystal, Property of A Lady and of course Kenneth J Lane.

Gems and Pearls Real and Fake

Jewels have always been used as love tokens and whilst many pieces were fine gems and precious metals, good fake jewellery intended to deceive existed.  True gemstones and pearls originated from the east and were bought chiefly by the Italians.  The Italian merchants then sold the goods on in Europe.  Good glass imitations were often used and sometimes with intent as in royal funerary robes and children's jewellery.

Flawless, round, natural, large white pearls were prized more than precious gemstones. The finest of pearls were provided by South India and the Persian Gulf, see good examples of pearl jewellery.  The Italians, particularly the Venetians and people from Murano, could make imitation glass gems and pearls that were very good likenesses of the real jewels.  Recipes for false pearls existed in 1300 when white powdered glass mixed with albumen (egg white) and snail slime, produced beads that were used as imitation pearls. 

Jewellery History - Arts and Crafts Jewellery

The new design philosophy of Arts and Crafts that sprang up after 1870 was a reaction to mass produced goods and inferior machine made products.  It was a reaction to the shoddy interior and ornamental products of the industrial revolution.  Leaders of the movement in England included William Morris and John Ruskin and they promoted simple Arts and Crafts of designs based on floral, primitive or Celtic forms worked as wallpapers, furniture and jewellery.
The polished stones used in Arts and Crafts jewellery gave a medieval, simpler, gentler, tooled hand made look and feel to items.  People inspired by the movement to produce work of a more individual nature included Liberty of London and Renee Mackintosh of Glasgow.  By 1900, Arts and Crafts as a movement declined, so Art Nouveau, a more ostentatious version started in France took root.

Victorian Jewellery

When Queen Victoria came to the throne in 1837 jewellery was romantic and nationalistic.  It gave attention to the pressure of European folk art, which later influenced the Arts and Crafts Movement.  Until mid century most western jewellery came from Europe, but soon jewellery began to be made in America and Australia.Picture of garnet necklace. Costume and fashion history of jewelry.

Although jewellery had been made by multiple methods of production for centuries, mid Victorian mass production in Birmingham (England), Germany and Providence, Rhode Island meant that standards were lowered.

Victorian women rebelled when they saw some of the machine made jewellery on offer, although much of what has survived is of good quality.  Many wore no jewellery at all, or bought from the artist craftsman jewellers who emerged at much the same time.

Some jewellers like Tiffany began to make fine jewellery of such high standard that they soon opened shops in main cities of Europe.

Fine and Fake Jewellery

Gold in Egypt 3000 BC

In the ancient world gold was the preferred metal for making jewellery. It was rare, did not tarnish and best of all it was malleable, so it could be worked fairly easily.

Magnificent bracelets, pendants, necklaces, rings, armlets, earrings, diadems, head ornaments, pectoral ornaments and collars of gold were all produced in ancient Egypt, the land of the Pharaohs.Picture of golden mask of Tutankhamun. Costume and fashion history of jewelry.

Excavations by Howard Carter in 1922 led to the great discovery of Tutankhamun's tomb and many gold funerary artefacts, all showing the art work of ancient Egypt.

Gold and Gems in Greece 1400 BC

Picture of Greek hoop earrings in gold. Costume and fashion history of jewelry.In ancient Greece, beads shaped as natural forms like shells, flowers and beetles were manufactured on a large scale.  Beautiful and delicate necklaces and earrings were found in burial sites in Northern Greece.  By 300 BC the Greeks were making multi coloured jewellery and used emeralds, garnets, amethysts and pearls.   Right - Greek earrings.

They also used coloured stones, glass and enamel.  Carved cameos of Indian Sardonyx (a striped brown pink and cream agate stone) along with filigree gold work were widely made.  Beads were made by joining two flat pieces of gold and filling them with sand.
Italian Gold and Roman Coinage

Eight centuries BC the Italian Etruscans in the Tuscany region produced granulated textured gold work.  They made large fibulae or clasps, necklaces, bracelets and earrings.  They also made pendants that were hollow and could be filled with perfume. The Italians are still renowned for high quality stylish trend making gold work today.

In coinage the Romans used 18 and 24 carat gold.  Being fairly easily available the coinage was the craftsman's raw material for decorative jewel work.  2000 years ago the Romans were using sapphires from Sri Lanka, cloudy emeralds, garnets, amber and Indian diamond crystals, in effect they they controlled the wholesale jewlery of the ancient world.  When England was under Roman rule, fossilized wood called jet from the North of England was carved into interesting pieces.
