Conclusions
-
1.
Increasing the silicon content of Fe−C alloys reduces the thickness of the carbonitride case obtained in low-temperature liquid cyaniding, the phase composition remaining unchanged.
-
2.
The formation of pores in the carbonitride layer at graphite platelets is due to impaired diffusion conditions in the pores surrounding graphite and to the evolution of adsorbed gases.
