| 摘 要： | 为了研究马氏体不锈钢的表面性能,采用等离子堆焊技术在Z5CND16-04不锈钢表面制备铁基合金堆焊层.采用扫描电子显微镜、能谱仪、X射线衍射仪、显微硬度计及销盘磨损实验机等检测设备,对堆焊层的组织结构、成分、硬度和磨损性能进行了研究.结果表明,铁基合金堆焊层主要由α-Fe、(Fe,Cr,Mo)7C3和(Fe,Cr,Mo)23C6相组成,添加稀土元素后相组成无明显变化.铁基合金堆焊层的硬度和耐磨性均明显高于马氏体不锈钢基材.添加适量的CeO2后,明显细化了堆焊层的显微组织.

| Abstract: | In order to study the surface properties of martensitic stainless steel, the Fe based alloy surfacing layer was deposited on the surface of Z5CND16-04 martensite stainless steel with the plasma surfacing technology. With such testing devices as the scanning electron microscope(SEM), energy disperse spectroscope(EDS), X ray diffractometer(XRD)and microhardness tester and pin-dish abrasion tester, the microstructure, composition, hardness and wear properties of surfacing layer were studied. The results show that the surfacing layer is composed of α-Fe,(Fe, Cr, Mo)7C3 and(Fe, Cr, Mo)23C6 phases. After adding the rare element(RE), the phase constitute has no obvious change. The hardness and wear resistance of Fe based alloy plasma surfacing layer are higher than those of martensite stainless steel substrate. After adding the moderate content of CeO2, the microstructure of surfacing layer gets obviously refined. |
