| 摘 要： | 利用激光熔覆技术在不锈钢基材表面原位合成了Ni3Al金属间化合物覆层。用XRD和SEM分析了覆层的相组成和组织结构。在CSM栓-盘摩擦磨损试验机上对覆层的高温摩擦磨损性能进行了测试。结果表明:覆层由单相Ni3Al金属间化合物组成;覆层与基材呈良好的冶金结合;覆层的摩擦因数和磨损率在500℃时具有最低值,分别为0.51和1.38×10-4mm3/Nm。 |
| 关 键 词： | Ni3Al 激光熔覆 摩擦磨损 |

| Abstract: | Ni3Al intermetallic compound coating was successfully in-situ synthesized by laser cladding on stainless steel surface.Crystalline phase composition and microstructure of the coating were characterized by X-ray diffraction and scanning electron microscopy.It is found that the coatings are composed of Ni3Al single-phase and exhibit good metallurgical bonding between Ni3Al coatings and stainless steel substrats.The tribological properties of the coatings at high temperature are evaluted using pin-on-disk test... |
| Keywords: | Ni3Al laser cladding friction and wear |
