① Properly involve parts structure to reduce stress concentration;
②Using processed or surface strengthening treatment to improve the quality of the working surface of the parts;
③Reasonably select the matching materials, lubricants and lubrication methods of the friction pair to improve the wear resistance of the parts;
④Choose corrosion-resistant materials to manufacture parts that work in corrosive media;
⑤Using heat treatment to improve the mechanical properties of parts materials, or using processes such as rolling and shot peening to generate favorable residual stresses on the surface of the parts, etc.
