It is known that the task of increasing the wear resistance of a particular product often does not involve a qualitative modification of the structural composition of the material used throughout its entirety, but is transferred to a modification of the surface layer of the material, since the protection of the mating parts from wear is in some cases solved by surface hardening. In the general case, surface hardening is understood as an increase in the hardness of the working surface of the part, which makes it possible to increase the wear resistance [2, 3].
To minimize the increase of the manufacturing cost, the concept of Lean-Alloy was introduced at the stage of alloy design and the high frequency induction heat treatment for surface hardening was controlled within our cycle time of mass production.
With surface hardening, the anticipatory effect of deep contact fractures (DCF) with a fundamentally different (from the surface) model of contact fatigue life is possible.
In addition, recent studies on cold roll-beating formation have shown that changes in the surface roughness and surface hardening of the workpiece are closely related to the generation of residual stress [8-10].
Repairing coatings and surface hardening takes lots of time and money, especially for a part with visual requirements.
Surface hardening with diamond-like carbon (DLC) nanocoatings can protect aluminum and steel molds against even abrasive glass-filled resins.

Specifically vacuum carburization gives higher hardness value at greater depth than any other surface hardening methods [10-11].
