Wear failure analysis
Wear failure analysis

Wear is the phenomenon that wear debris is gradually separated from the surface of the object under the action of friction. Wear failure refers to the failure of mechanical parts to achieve the original design effect due to the occurrence of wear phenomenon, that is, to reach the original design level. Wear failure is a process of gradual development and gradual change, which is short for several hours and long for several years. Wear, fracture and corrosion are called three forms of metal failure analysis, and its harm is very amazing.            According to the failure mechanism of wear, wear can be divided into:            ① adhesion wear;            ② abrasive wear;            ③ surface fatigue wear;            ④ corrosion and wear.            According to the wear state of the surface of the parts, it can be further divided into:            ① continuous wear;            Adhesive wear;            ③ fatigue wear;            ④ abrasive wear;            ⑤ corrosion and wear;            ⑥ fretting wear;            ⑦ surface plastic flow.
