How to Test Hardness of Cemented Carbide?

The hardness of the metal is the ability of the metal material to resist local deformation, especially plastic deformation, indentation or scratching. It is an indicator to measure the degree of softness and hardness of the metal material. It can sensitively reflect the chemical composition, metallographic structure, Differences in heat treatment process and cold working deformation, etc., testing the hardness of metal materials is essential in production, scientific research and engineering.

The hardness test can be generally divided into two types: press-in method and scribing method according to the different stress methods. In the press-in method, it can be divided into static test method and dynamic test method according to different forcing speed. Among them, the static test method is the most commonly used, and common static test methods such as Brinell hardness, Rockwell hardness and Vickers hardness are common.

Cemented carbide is an alloy material made of hard compound and bonding metal of refractory metal through powder metallurgy process, and it usually contains metal elements such as tungsten, cobalt and titanium. Carbide has a series of excellent properties such as high hardness, toughness, wear resistance, heat resistance, corrosion resistance, and high temperature resistance. It is known as "industrial teeth" and is mostly used to manufacture cutting tools, knives, wear-resistant parts, etc , Widely used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields.
