Influence of the temperature of vacuum carburizing on the thickness of the carburized layer and properties of steel parts

09 Feb 2021

The properties of steel parts after carburizing in low-pressure acetylene are studied. The thickness of the carburized layer, its hardness, the microstructure, and the hardness of the core are determined after carburizing at 900 – 960°C with simultaneous shortening of the process from 104 to 44 min. The data obtained for the diffusion of carbon make it possible to predict the profiles of carbon distribution over the thickness with good enough accuracy.
