The nature of the abrasive
The hardness, particle size and shape of abrasive have great influence on wear.The results show that the higher the hardness of abrasive is, the more serious the wear is.Material increases with the size of wear and wear rate increase, but the particle size increases to a certain critical value material wear rate almost unchanged or changes very slowly, polygonal wear particle under the same conditions than the ball round grits wear large amount of 4 times, relatively speaking, a greater influence on the abrasive particle shape on the ductile materials, smaller influence on brittle materials.
The nature of the target
The hardness, toughness and elastic modulus of the target material are decisive factors to determine whether the material is wear resistant. Generally speaking, the higher the hardness, the better the toughness and the greater the elastic modulus of the target material are, the better the performance of the material will be.However, whether the hardness, toughness and elastic modulus of the target are suitable for a certain working condition does not completely depend on the material itself, but largely depends on the change of the external environment, which is also the essence and key point of anti-wear.
Incidence rate
The experiment shows that the speed has the greatest influence on the wear, and the wear is proportional to the third power of the speed.
Angle of incidence
Incident Angle refers to the included Angle between the target surface and the trajectory of incident particles. When the incident Angle is very low, the kinetic energy component of the incident particles in the direction perpendicular to the material surface is not enough to cause serious damage to the material. Brittle materials show the advantages of high hardness and show a lower erosion rate than ductile materials.
