Factors Related To Wear Failure Of Grinding Steel Balls(2)

1. Angle: The impact angle in erosion wear and wear has a great influence on the wear. The impact angle has different effects on brittle and ductile materials. For brittle materials such as ceramics, the wear amount increases with the increase of the angle, and the wear amount is the largest under the vertical impact condition close to the 90° angle, indicating that the brittle material is not suitable for use under the large-angle impact condition; for the ductile material, the wear amount is the first Increases with increasing impact angle, reaches a maximum at a certain angle, and then decreases with increasing impact angle. This shows that ductile materials are easy to wear when working under low-angle conditions, and can give full play to their wear resistance under high-angle conditions. This is because the hardness of ductile materials is low, and the abrasive particles are most beneficial to the cutting of the surface during low-angle erosion, and the wear amount increases.

5. Temperature: Wear increases with increasing temperature.

6. Humidity: In actual engineering, in the case of metal friction pairs, the liquid enters the grinding interface, and the wear can be greatly reduced; however, when the abrasive is worn, water enters the abrasive, and the wear becomes serious.

7. Particle size: Abrasive particle size: The effect of wear initially increases linearly with particle size. When a certain value is reached, the so-called critical particle size, the increase in wear becomes slower, or no longer increases. More meaningful is the relative hardness or hardness ratio of the material to the abrasive.
