Ni-P-金刚石/TiAlN双层涂层的耐磨性能研究

摘要

Ni-P-C/TiAlN double-layered coatings were prepared on 304 stainless steel by the composite electroless plating and multi-arc ion plating.The SEM,friction-abrasion testing machine and electronic balance was used to study the friction and wear performance of coatings.Ni-P,Ni-P-C,TiAlN coatings those were prepared in the same conditions were compared with the Ni-P-C/TiAlN double-layered coatings.The experimental results show that the friction coefficient of Ni-P-C/TiAlN coating is slightly higher than Ni-P-C coatings,but it is significantly lower than Ni-P and TiAlN films.The weight loss of the friction pair of the Ni-P-C/TiAlN coating is biggest in the four kind of coatings,indicating the Ni-P-C/TiAlN coating has the best wear resistance.%采用化学复合镀和多弧离子镀的方法,在304不锈钢基材表面制备Ni-P-金刚石/TiAlN双层涂层,采用SEM、磨损试验机、电子天平、光学显微镜研究涂层的摩擦磨损性能,并与相同条件下制备的Ni-P、Ni-P-金刚石、TiAlN涂层进行对比.结果表明,Ni-P-金刚石/TiAlN双层涂层的摩擦系数比Ni-P-金刚石涂层略高,但明显低于Ni-P涂层和TiAlN涂层,摩擦副的质量损失最大,具有最好的抗磨损性能.
