Abrasives are a general term for abrasives and abrasives, including abrasive products and abrasive products. Abrasive wear is generally caused by the relative movement of the abrasive and the surface of the part. The force on the abrasive can be decomposed into the component perpendicular to the surface and the component force parallel to the surface. It sometimes wears out during use, so the effects on abrasive wear in terms of abrasive properties are:

1. The influence of the shape of the abrasive particles. The main mechanism in the process of sliding abrasive wear is micro-cutting, which produces abrasive chips on the surface of the cutting metal material like a tool.

2. The influence of abrasive hardness. Hard abrasive wear increases the hardness of the material and does not increase its wear resistance significantly. Soft abrasive wear increases the hardness of the material and rapidly increases the wear resistance.

3. The influence of the movement mode of the abrasive on the wear of the material. The state of motion of abrasives and materials can be divided into sliding, rolling and impact wear.

4. The influence of abrasive grain size. There is a critical dimension of the abrasive. When the load is small (when the nominal contact stress is low), the abrasive grain size less than the critical ruler has a significant dependence on the wear rate of the material. When the abrasive grain size exceeds this critical dimension, the wear rate of the material does not increase as the abrasive grain size increases. In some cases, when the particle size is less than a certain value, the wear of the material tends to zero, which indicates that the wear of the material is negligible during some "grinding" processes. When the load is large, the abrasive grains smaller than the critical size cause greater wear on the material; the wear caused by the abrasive grains larger than the critical size also increases with a certain slope with the increase of the load, and the larger the load, the larger the slope.
