MODIFIED LOW TEMPERATURE CASE HARDENING PROCESSES

摘要

An iron-containing workpiece is case hardened by low temperature carburizati on during which one or more process steps - including adjusting the carburizati on temperature, adjusting the concentration of carburization specie in the carburization gas and reactivating the surfaces to be carburized - is carrie d out to enhance the overall rate and uniformity of carburization with minimiz ed soot generation, whereby carburization can be completed faster than possible in the past.
