introduction：So-called wear，It refers to the process of continuous loss or residual deformation of material on the working surface when the dual surface of the moving pair moves relative to each other。The wear process is mainly due to the mechanical interaction between the dual surfaces，Sometimes it is produced by chemical action。Usually this mechanical action refers to the action of friction，Chemical action often refers to the erosion of environmental media and chemicals。When lubricated with grease，Grease film can reduce the wear of the dual surface and prevent the entry of aggressive substances。 wear、Aging and fracture are the three main causes of damage and failure of mechanical parts。Run-in only during the initial stage of wear or minor wear(run
