Conclusions
-
1.
Cyaniding of steel by paste with the use of induction heating is a progressive method of chemical and heat treatment. The use of active paste on heating to 1200°C ensures within 30–35 sec, a diffusion layer having a thickness of 0.3 mm.
-
2.
After quenching, the microhardness of the diffusion layer, depending on the heating conditions, can reach Hμ=1100.
-
3.
The diffusion layers are plastic and have a high corrosion resistance. Short-time high-temperature heating does not cause a noticeable growth of austenite grains.
