BC(C,T)/FCC	99.8/0.2	98.2/1.8	96.3/3.7	98.5/1.5
Carbides-based	Cr, Mo	Cr, Mo	-	Cr, Mo, V
von Mises stress	Low level, minimal fluctuations	Lower residual stress, more uniform	Significant, pronounced maxima at surface and in center	Overall low level, reduced surface value
Hydrostatic stress	Very low level, uniform—except surface	Low level, uniform—except surface	Parabolic-like distribution, tensile near the surface	Parabolic-like distribution, tensile near the surface
Overall characteristics	Low residual stress and uniform distribution	High hardness, improved strength of the material	High hardness and residual stress on the surface, risk of surface cracking	Improved residual stress level
Potential applications	Suitable for less demanding applications	Demanding applications	Demanding application with certain limitations	Suitable for more demanding applications (fatigue resistance)
