摘要/Abstract

摘要： 为了满足QT500-7球墨铸铁在长期恶劣工况下的耐磨性和抗氧化性能的要求,采用激光熔覆技术在该球墨铸铁表面制备ZrB₂-Ni基复合涂层。通过XRD、SEM和EDS分析了复合涂层的微观结构和相组成,并测试了涂层的硬度、摩擦学性能和高温抗氧化性能。结果表明,激光熔覆ZrB₂-Ni基复合涂层组织均匀致密,物相主要为γ-Ni、NiC_x、Ni₃B、Ni₂Si、Ni₃Zr和Zr₅Si₄。与基体相比,10%ZrB₂-Ni基复合涂层的平均硬度为448 HV0.2,提升了约87%,磨损质量损失和磨损率降低了约56%,基体表面熔覆10%ZrB₂-Ni基复合涂层氧化100 h后增重6 mg/cm²,减少了约65%。ZrB₂-Ni基复合涂层显著提升了球墨铸铁表面的耐磨和高温抗氧化性能。

Abstract: In order to meet the requirements of wear resistance and oxidation resistance of QT500-7 ductile iron under long-term harsh working conditions, the ZrB₂-Ni based composite coating was fabricated on the surface of the QT500-7 ductile iron by laser cladding technology. The microstructure and phase composition of the composite coating were analyzed by means of XRD, SEM and EDS, and the microhardness, tribological properties and high-temperature oxidation resistance of the coating were tested. The results indicate that the microstructure of the laser clad ZrB₂-Ni based composite coating is uniform and dense, and the phases mainly consist of γ-Ni, NiC_x, Ni₃B, Ni₂Si, Ni₃Zr and Zr₅Si₄. Compared with the substrate, the average microhardness of the 10%ZrB₂-Ni based composite coating is increased by approximately 87%, being 448 HV0.2, and the mass loss and wear rate are reduced by about 56%. The mass gain of the substrate surface cladded with 10%ZrB₂-Ni based composite coating after oxidation for 100 h is 6 mg/cm², decreased by about 65%. The ZrB₂-Ni based composite coating significantly enhances the wear resistance and high-temperature oxidation resistance of the ductile iron surface.
