对钴基Ｓｔｅｌｌｉｔｅ合金Ｄ８０２焊条、镍基ＮＤＧ－２粉末、Ｄ５４７Ｍｏ焊条和Ｄ５０７Ｍｏ焊条制备的阀门密封面堆焊层，进行了从室温至６００℃的粘着磨损试验研究．结果表明：组对材料、组对方式和粘着磨损试验温度都会影响堆焊层的耐磨性．结合堆焊层的高温硬度试验、高温金相和电子金相分析，探讨了高温粘着磨损的机理． Cobalt-based Stellite alloy D802 electrode, nickel-based NDG-2 powder, D547Mo electrode and D507Mo electrode sealing surface preparation of the welding seam, from room temperature to 600 ℃ adhesion wear test study. The results show that the wear resistance of the surfacing layer is affected by the group-to-part, group-to-part and sticking wear test temperatures. Combined with the high temperature hardness test of surfacing layer, high temperature metallography and electronic metallographic analysis, the mechanism of high temperature adhesive wear was discussed.
