| 摘 要： | 在真空熔结镍基合金涂层(成分是0．65％C-24％Cr—3．5％Si-3．5％B-3．0％Mo-6％Fe-Ni余量)与65Mn钢组成的滑动磨损系统中，研究了磨屑的演变机理。磨损过程中磨屑不仅存在氧化、碎化等化学、机械过程，还存在因相互挤压、粘结甚至微区热压烧结等冶金过程，两方面的共同作用，使氧化物磨屑成分均匀化。应用Fe-Ni-O系统相图对高温磨损磨屑进行相分析。

| Abstract: | Change mechanism of wear debris has been researched in shding wear system composed of iron-base alloy coating (0.65%C-24% Cr-3.5%Si-3.5%B-3.0%Mo-6%Fe-Ni bal.) with 65Mn steel. During wear process, not only chemical and mechanical change such as oxidating and breaking etc. take place in debris, but also metallurgical course such as adhesing especially hot press sintering at small areas in debris because of hot extruding. Because of the two side effects mentioned above, the composition of the debris has become homogeneous. Fe-Ni-O system phase diagram has been used to analyze phases existing in the wear debris. |
