The use of solid phase change on parts of the surface layer by a rapid heating method known quenching surface treatment, commonly known as surface hardening. Flame Hardening high (medium) frequency induction hardening, laser heating or electron beam heating and quenching. The characteristics of these methods is: local heating surface quenching small deformation of the workpiece; heating speed, high production efficiency; heating time is short, very slight surface oxidation and decarbonization. The metal surface layer is plastically deformed by mechanical methods, thereby forming a hardened layer of high hardness and high strength, such a surface hardening method is called surface deformation strengthening, also known as work hardening. Including shot blasting, sand blasting, cold extrusion, rolling, cold grind and impact, explosion Shock. The characteristics of these methods are: reinforcing layer dislocation density increased, alkylene crystal structure refinement, and thereby improve the hardness and strength, the surface roughness value is decreased, can significantly improve the fatigue strength of parts of the surface and reduce fatigue notch sensitivity . This fortification process is simple, the effect is significant, there is no clear boundary between the hardened layer and the substrate, coherent structure, not easy to fall off in use. The majority of the method has been applied in bearing industry: the rolling elements surface impact strengthen the application of such methods, precision rolling rings have become the new processing and fortification.
