Surface hardening,treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft.The combination of a hard surface and a soft interior is greatly valued in modern engineering because it can withstand very high stress and fatigue,a property that is required in such items as gears and anti-friction bearings.Surface hardening (case-hardening) - tec-scienceSurface hardening is used to produce a hard and wear-resistant surface layer on steel workpieces,while the toughness in the core is largely retained.Home; Introduction.A hard surface layer is essential to increase the wear resistance of contacting components.In these cases hardening can be used as a possible heat treatment.Surface Hardening of Steels - Total MateriaIntroduction to Total Materia 4 th June 2015.About us.Company; Further,the surface hardening of steels has an advantage over through hardening because less expensive low-carbon and medium-carbon steels can be surface hardened without the problems of distortion and cracking associated with the through hardening of thick sections.

Mechanical means of hardening the surface of steel parts include peening,which is the hammering of the heated surface,as by iron pellets shot onto the surface or by air blasting,and cold-working,which consists of rolling,hammering,or drawing at temperatures that do not affect the composition of the steel.surface hardening metallurgy Britannica
