【摘要】 用高能等离子束在常压下快速扫描涂敷合金粉末的１６Ｍｎ钢表面，实现了表面合金化及自激冷淬火。透射电镜分析表明：合金化层组织细小，并产生了ＦｅＢ、Ｆｅ３Ｂ、Ｆｅ３（Ｓｉ，Ｂ）等合金相。１６Ｍｎ钢经上述复合处理后表层硬度可达５９５ＨＶ００５（５６ＨＲＣ）。更多还原

【Abstract】 The surface alloying and quenching for 16Mn steel were simultaneously taken place through plasma jet rapid scanning on the surface coating at ordinary pressure. TEM observation showed that the microscopic structure was obviously fined and the new phases such as FeB, Fe3(Si,B), Fe3SiB2, Fe3C and Fe3B were generated. The microhardness of alloying layer reached at 595HV005 (56HRC).更多还原
