Wear and tear and wear is also known as peeling, is a common form of wear and tear. With the increase of the use of time can be observed. Wear generally divided into the adhesive wear and abrasive wear. Adhesive wear may occur in two relative sliding mating surface, material transfer from one surface to another surface, accompanied by the friction heat and rough surface. Can lead to bad lubrication, cause the material to hardening tempering, lead to local stress concentration, cracks. Wear and abrasive wear is divided into grits polishing wear. For mild wear of abrasive wear performance, specific route trace, matt surface. Can lead to decrease the lubricant performance, wear fast race, rolling element and cage. Worn surface polishing luster, raceway and rolling body wear serious still is like a mirror, can make the roller or raceway surface produce plastic deformation. Indentation indentation is due to the hard particles into the raceway and rolling body, and crushed, and then to race or rolling on the surface of the body surface plastic deformation. May come from the pollution of external or internal hard particle wear, such as metal fatigue spalling of debris. Is generally due to external contaminants, or internal wear loose particles, as well as the insufficient lubrication. Initial peeling metal fatigue often development from already wear, deformation or damage to the metal surface. The resulting metal flake is worn the secondary losses, is caused by worn parts of existing stress concentration. Common causes are wear or debris pits; Brinell creasing or false brinell indentation; Bad lubrication. Invalid lubrication and impurity content of raw materials. The other nine kinds of failure analysis, please continue to pay attention.
