Conclusions
-
1.
Carbonitriding increases the red hardness of steel 4Kh2V5MF.
-
2.
The optima carbonitriding conditions to improve the wear resistance and red hardness of the steel are 560° for 90 min.
-
3.
The higher red hardness is probably due to the formation of special vanadium and tungsten carbides in the surface layer at 560°.
