Influence of Deep Carburizing Treatment on Hardness of Workpieces
Journal Title: RECENT - Year 2012, Vol 13, Issue 36
Abstract
In carburizing heat treatment was achieved a theoretical and experimental research of influence of carburizing time on hardness and depth. The study of obtained results through performed experiments leads to optimization of carburizing process by application of an annealing treatment of diffusion to obtain a corresponding carbon concentration on great depths. The carburizing atmosphere determines the rate of carbon transfer from the atmosphere to the steel surface, in the carburizing stage. In the annealing stage, the rate of carbon transfer becomes limited by the carbon diffusion in austenite, which is primarily determined by the carburizing temperature and alloy composition of the steel. Is established during the studies presented in this papers, possibility of successfully implementing a deep carburizing process concept with all the advantages derived from this and is presented the advantages of use of diffusion annealing and its influence on hardness of carburized layer.
