采用等离子喷涂技术在铬锆铜(CrZrCu)基体表面制备了Cr3C2 p/NiCr涂层。利用X射线衍射仪(XRD)、扫描电镜(SEM)等仪器研究了涂层的显微组织及结构,采用磨粒磨损试验机对Cr3C2 p/NiCr涂层与电镀NiCo层的磨损性能进行了测试比较。结果表明:涂层组织呈片层状结构,在NiCr合金片层上分布着未熔的Cr3C2和Cr7C3、Cr2Ni3、CrNi析出相。与电镀Ni-Co镀层相比,Cr3C2 p/NiCr涂层具有较高的硬度和耐磨粒磨损性能,其磨损量仅为电镀层的35%。 The Cr3C2p / NiCr coating was prepared on the CrZrCu substrate by plasma spraying. The microstructure and microstructure of the coating were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The wear performance of Cr3C2 p / NiCr coating and NiCo plating layer was tested by abrasive wear tester Compare The results show that the microstructure of the coating is lamellar structure, and the unmelted Cr3C2 and Cr7C3, Cr2Ni3 and CrNi precipitates are distributed on the NiCr alloy sheet. Compared with the electroplated Ni-Co coating, Cr3C2 p / NiCr coating has higher hardness and abrasive wear resistance, and the wear amount is only 35% of the electroplating layer.
