What causes an abrasive wear

(A) What is the abrasive wear
Abrasive wear is due to a friction surface of the convex part and the other hard-surface contact between the friction surface or both the hard particles exist in the event of relative movement of the  Abrasive paper  two surfaces of the one surface or both surfaces of the material is transferred signs of wear. (Two) abrasive wear mechanism
The abrasive surface of the part relative movement, the force on the abrasive can be decomposed into a component force perpendicular to the surface of the force parallel to the surface.
1 perpendicular to the surface embedded in the surface of the abrasive component, good material for the plastic surface indentation large dense, repeated action, resulting in fatigue and damage, the brittle materials do not produce distortion on the surface of brittle fracture.
(2) parallel to the surface of the abrasive component tangential movement generated, resulting surface is scored, and the cutting groove is left, the plastic material, the abrasive cutting surface of the friction will cut a chip.
For brittle materials, abrasive cutting once cut from the surface of a lot of debris.
Abrasive wear rate is very large, many major damage in the form of machinery and equipment. (C) the main factors affecting abrasion
1 abrasive particle size effect on the  cutting and grinding disc amount of wear
Abrasive wear of the metal with the increase of the size, when the abrasive size increases after a certain size, the wear rate is constant.
(2) the geometry of the abrasive wear of the
Sharp angular abrasive abrasive wear than the sleek, high-speed, abrasive be blunt, the wear rate of decline, if the abrasive is ground, the grinding speed will increase.
3 Abrasive effect of hardness on the amount of wear
Thus, the enhanced surface hardness of the part approaches or exceeds the hardness of the abrasive, to improve the wear resistance of parts, but the high hardness of the material, will cause decrease in toughness, increased brittleness and other consequences. (1) Abrasive hardness is lower than the hardness components, the wear amount of the difference in hardness between the two, the difference increases, the wear rate decreases. (2) slightly higher than the hardness of abrasive hardness parts, then wear serious, reduce the difference between the hardness and wear is reduced. Thus, the enhanced surface hardness of the part approaches or exceeds the hardness of the abrasive, to improve the wear resistance of parts, but the high hardness of the material, will cause decrease in toughness, increased brittleness and other consequences.
4 Pressure effect on wear
Against abrasive wear, the wear rate is proportional to pressure on parts made of the same material, the pressure reduced by half, increasing life expectancy doubled. (Four) measures to reduce abrasive wear
1 to reduce the entry of abrasive
Such as configuring various filters, increase the  non woven flap wheel dust seal means mounted to a magnet, crumb room and oil pollution indicator, often clean replacement air, fuel, oil filtration devices. 2 Enhanced abrasion resistance of parts
Heat treatment and surface treatment method to improve the properties of the part material, increasing the surface hardness than the hardness of the surface as the hardness of the abrasive.
3 selection of good wear resistance of the material
Parts are made of carbon steel for quenching, tempering, get martensitic steel parts with both approaches can wear, but also has good toughness. Abrasive wear will not only damage the machinery and equipment, but also reduce the life and efficiency of abrasive, abrasive production base metals as China Shandong Kai Tai Group Co., Ltd. not only provide you with high quality metal abrasive, but also to provide customers with full azimuth solution, the following is a summary of Shandong Kai Tai finishing abrasive wear of the main factors and preventive measures.
