Study on the Forming and Self-Repairing of Ni60A/MoS2 Composite Lubricating Film
Based on the research of the tribological properties of the Ni60A/MoS2 composite coating, this paper has studied the forming and self-repairing mechanism of MoS2 lubricating film. The study shows that the forming mechanism includes four stages: the friction beginning stage, MoS2 precipitating stage, MoS2 covering stage and MoS2 forming stage. The destroying processes of the composite lubricating film includes the film thickness decreasing, the crack emerging, the crack expansion, the lubricating film flaking. Meanwhile, the hard particles piercing into the lubricating film also results in the abrasion destroying of the lubricating film and greatly shortening the lifespan of the lubricating film.
