Tungsten Carbide Blades and Coatings

We are all aware that hardness is the primary criterion for consumers of tungsten carbide blades. Blades with high hardness may significantly increase flexibility, working speed, service life, etc. But how to make a tool harder is a challenge since not all tools made by manufacturers and sold on the market have benefits in terms of hardness. Several requirements must be satisfied for this type of milling cutter's hardness to rise. One is to use high-quality materials.

This is a crucial prerequisite, but many manufacturers use subpar tungsten carbide materials, either because their own production requirements aren't met or to cut costs. As a result, it's challenging to achieve better hardness because the material lacks hardness and it's challenging for the tool to demonstrate hardness. The manufacturer determines the type of tungsten carbide material to use. One is that the manufacturer needs to be capable of adapting its output and have a commensurate reputation. High-quality tungsten carbide materials will only be utilized to guarantee the tool's hardness if these two milestones have been attained.

Along with material advancements, high-hardness tungsten carbide cutting tools also require higher craftsmanship since, no matter how excellent the tungsten carbide materials are, they must be better when the craftsmanship satisfies the requirements. Production needs, for instance, make it difficult to restore the original hardness of high-quality tungsten carbide following degradation because of high temperature and the manufacturer's inability to create the material. There are several hot environments used in the forming and welding processes used to make these tools. Without advanced technology, the high temperature will cause the tungsten carbide substance to degrade.

Adding various coatings will also have different effects. Coating tungsten carbide has two methods: one is CVD, and the other one is PVD. The principle of chemical vapor deposition is the thermally induced chemical reaction at the surface of heated tungsten carbide blades, which is also developed to adapt to new materials and the semiconductor industry. PVD is a vaporization technique to deposit a thin layer of material on tungsten carbide blades. Coatings have extremely high hardness and wear resistance. Compared with tungsten carbide blades without coatings, tungsten carbide blades with coatings can work at a higher cutting speed, which can improve manufacturing efficiency.
