三种渗碳结构钢经不同化学热处理后耐磨性的研究

Study on the wear resistance of three carburizing structural steel after different chemico-thermal treatment

研究了经渗碳、碳氮共渗、氮化处理后18Cr2Ni4WA、27SiMnMoV和25SiCrMoV钢的耐磨性。结果表明 ,经三种不同化学热处理后,25SiCrMoV钢的耐磨性最好 。

The wear resistance of 18Cr2Ni4WA,27SiMnMoV and 25SiCrMoV steel after carburizing ,carbonitriding and nitriding trearment is studied.The results show that the wear resistance of 25SiCrMoV steel is the best and that of 18Cr2Ni4WA steel is the worst after three different chemico-thermal treatment.
