ZrN Coating Tungsten Carbide Coated Tools Introduction

Tungsten carbide coated tools in addition to ZrN coatings resistant to corrosion, high temperature, wear resistance, but also has good mechanical properties and electrical conductivity, beautiful golden appearance and so on. ZrN coating has been widely used in electronic circuit electrical contact layers, the jewelry industry and mechanical friction decorative layer of anti-friction layer, but not a common tool coating applications. With advances in machinery manufacturing technology continues to high-precision, high-speed direction, so the cutting tool in strength, high temperature, wear resistance and service life and other aspects of the performance requirements is also rising. The tool coating treatment is one of the important means to improve the performance of the tool. Because coating can improve the processing efficiency and accuracy, longer tool life, reduce processing costs, and therefore, the coating of metal cutting tools used in more and more widely.
