Conclusions
-
1.
In the process of nitriding at 500–590° the γ'-phase is alloyed with tungsten and the solubility of nitrogen in ferrite increases. The microhardness of the case also increases.
-
2.
The combination of high-temperature nitriding with subsequent quenching makes it possible to obtain a case with a fairly high hardness.
