Related knowledge about alloyed coating

Alloyed Coating is a thin layer of wear-resistant TiC or TiN that is coated on the surface of the cemented carbide blade by a coating method. Because of its high hardness, strength and wear resistance, it is known as the "industrial teeth", which can be used to manufacture cutting tools, knives, drilling tools and wear-resistant parts, and are widely used in military, aerospace, drilling, Mining tools and other fields. However, the strength and hardness of cemented carbide cannot meet the development needs of modern industrial alloys at the same time, so coatings that can improve the wear resistance of cemented carbide have emerged.

The main purpose of the alloyed coating is to further improve the wear resistance of the cemented carbide, and also to extend the life of the alloy tool, as well as:

1. Improve the performance of cemented carbide tools;

2. The needs of high-speed cutting and high-speed machining;

3. The need for machining difficult-to-process materials such as aviation heat-resistant alloys, composite materials, and hard materials.

Features of hard alloy coating:

The preparation processes of alloyed coating mainly include high temperature chemical vapor deposition, physical vapor deposition, plasma chemical vapor deposition and ion-assisted physical vapor deposition. Different processes have different coating mechanisms, advantages and disadvantages.
