采用超音速电弧喷涂工艺在2Cr13马氏体不锈钢基体上制备了Ni-Ti涂层。用X射线衍射研究了涂层的相组成,用扫描电镜对涂层的显微结构和磨损后形貌进行了分析,测试了涂层的显微硬度,在橡胶轮磨粒磨损试验机上研究了涂层的耐磨粒磨损性能。结果表明,Ni-Ti涂层主要组织为NiTi(B2)相和一定量的TiO、NiO等氧化物,该涂层不仅有较高的硬度,而且较2Cr13基体有更加良好的耐磨粒磨损性能。 The Ni-Ti coating was prepared on a 2Cr13 martensitic stainless steel substrate by supersonic arc spraying. The phase composition of the coating was studied by X-ray diffraction. The microstructure and wear morphology of the coating were analyzed by scanning electron microscopy. The microhardness of the coating was tested. On the rubber wheel wear tester, Coating wear-resistant grain wear performance. The results show that the main microstructure of Ni-Ti coating is NiTi (B2) phase and a certain amount of TiO, NiO and other oxides. The coating not only has higher hardness, but also has better abrasion resistance than 2Cr13 matrix .
