Modified low temperature case hardening processes |
摘要 |
An iron-containing workpiece is case hardened by low temperature carburization during which one or more process steps-including adjusting the carburization temperature, adjusting the concentration of carburization specie in the carburization gas and reactivating the surfaces to be carburized-is carried out to enhance the overall rate and uniformity of carburization with minimized soot generation, whereby carburization can be completed faster than possible in the past.
