Wherein abrasive wear refers to the phenomenon of loss due to relative motion of the working surfaces in mutual motion, which wear is only present on all working surfaces in relative motion, and thus it takes a large proportion of mechanical wear; the adhesive wear refers to a working surface which moves relatively under high-speed heavy load, and under the action of tangential force, the contour peak of the surface is bonded at each point under the interaction due to overlarge load or overhigh instantaneous temperature; other wear refers to wear phenomena other than the above two types of wear, such as oxidation burning loss caused by high temperature of mechanical equipment working in a high temperature state or loss caused by plastic deformation caused by low strength; the comprehensive mechanical properties include high stress impact wear and low stress contusion wear; the high-stress impact wear refers to that the impact force applied to the surface of the metal material under the working condition is smaller than the impact force generated by chiseling wear; low stress contusion wear refers to the fact that under such operating conditions, the surface of the metal material is subjected to substantially no or little impact load;
