Low-temperature carbonitriding of cast iron

Abstract

1. We determined the optimal composition of the atmosphere for carbonitriding of malleable iron and gray cast iron to obtain the required thickness of the e and γ zones and surface hardness of the coating. 2. A relationship was found between the depth of the individual zones and the carbonitriding temperature and time. 3. Gray cast iron carbonitrided at 700° has a high wear resistance under conditions of friction without lubrication under high loads.
