摘　　要：用常规二段气体渗氮排出的废气对４０Ｃｒ、３８ＣｒＭｏＡｌＡ钢进行渗氮试验，并对废气渗氮与常规二段气体渗氮试件表面硬度、渗层深度、显微组织及脆性等分析比较．结果表明，采用气体渗氮排出的废气进行渗氮可以达到技术要求，节约能源，降低生产成本，提高经济效益和社会效益．The gases-nitriding tests of the 40Cr,38CrMoAlA steels have been done with relief-gases in the conventinal two stage gases-nitriding processing, and the microstructure, suface hardness, and brittleness of the relief -gase-nitriding and the conuentinal two-stage-gases-nitriding exemplares has been compared. The result cleared that; It can to save energy source,to reduce the production cast,and to increace the economical benefit which with the relief-gases in the gases-nitriding processing to be gases-nitriding.
