Tungsten Carbide Coated Tools Development

Tungsten carbide coating method continues to progress, becoming more complex and diversified, so that the corresponding tungsten carbide coated tools development. Tungsten carbide coating method from the initial development of high-temperature chemical vapor deposition coating is a plasma chemical vapor deposition coating, the temperature chemical vapor deposition coating and ion-assisted physical vapor deposition coatings. Development direction carbide coating method is a physical vapor deposition.

Carbide coating types are constantly updated from a single compound coating towards the development of diverse and complex compound coating; coating layers from several layers to a dozen layers; a new type of coating substrates has also been introduced, carbide coating substrates with a graded structure of cemented carbide coated tool performance is further improved; the coating process not only upgrading, but also to achieve a flexible combination of a variety of techniques to obtain a high performance carbide coating Layer tool.
