| 中文摘要: |
| 将 NiCr-Cr3C2 复合粉和 Ni 包 MoS2 粉按不同比例混合,制成三种喷涂粉末,采用等离子喷涂技术在 304 不锈钢表面制备复合自润滑涂层,并对涂层的物相组成、显微组织及摩擦磨损性能进行了研究。 结果表明:三种涂层的物相组成相同,主相均为 Cr7C3,Ni 和 MoS2;涂层与基体的结合为机械结合,孔隙率较低,表面有少量微裂纹;喷涂粉末中的 Ni 包 MoS2 粉偏少或偏多都会导致涂层的摩擦磨损性能变坏,Ni 包 MoS2 粉质量分数为30% 时,涂层的摩擦系数及磨损率最低,分别约为 0 . 36 和 3 . 3 X10-4mg / s。 |
| 英文摘要: |
| NiCr-Cr3C2based self-lubricating composite coatings of different content of cladded MoS2by Ni powder were deposited on 304 stainless steel by plasma spraying technology. The phase composition, microstructure and frictional behaviour of coatings were reasearched. The results indicate that the kinds of coatings have same phase composition, whch is Cr7C3, Ni and MoS2. Mechanical bonding forms between coating and substrate, the porosity of coatings is low, a small amount microcrack exsists on the surface of coatings. Excessive or scarce cotent of cladded MoS2by Ni powder in the coatings can induce worsening of frictional behaviour, the lowest value of friction coefficient and wear rate are separately 0 . 36 and 3 . 3 X10-4mg / s, which the content of cladded MoS2by Ni powder in the coatings is 30 % . |
