introduction：1.Frictional compatibility The property of preventing adhesion and boundary lubrication when the bearing diameter is in direct contact with the bearing bush。The material factors that affect the friction compatibility of friction pairs are：（1）The degree of difficulty in forming alloys in metallurgy。（2）Affinity of material to lubricant。（3）Friction factor of the auxiliary material in the non-lubricated state。（4）Microstructure of materials。（5）Thermal conductivity of the material。（6）The size of the surface energy of the material and the characteristics of the oxide film。2.entrapability The material allows foreign hard particles in the lubricant to clamp in and prevent scratching or scratches（and）The ability of abrasive particles to wear。For metal materials，Low hardness and elasticity
