Wear-resistant ceramic and cemented carbid materials are used in various equipment where protection from prolonged exposure to abrasive particles is required.

Wear of parts as a result of moving and grinding large volumes of solid particles or suspensions can be unexpectedly large, even if the particles are not considered too hard. The resulting wear is a combination of erosion due to collision with particles at large angles and abrasive wear at small angles of collision with particles where plastic wear mechanisms predominate. The wear mechanism depends on a number of variables: the size of the particles, the “sharpness” of their shape, mass, speed, hardness, applied load and angle of abrasive incidence. When selecting wear-resistant products, other factors should be taken into account: operating temperatures and the risk of corrosion.

At the same time, the products should maintain their operational properties for a maximum time.

Accordingly, the following requirements are imposed on wear-resistant products for the mining industry, crushing, separation:

• hardness;
• wear resistance;
• mechanical strength;
• corrosion resistance;
• low or high density;
• high degree of reliability and economy in operation.
