AI Technical Summary
Technical Problem
Existing sliding components with solid lubricant particles in the surface layer face issues of particle loss leading to unstable friction coefficients and poor sliding characteristics.
Method used
A sliding component with an iron substrate containing graphite particles and a tin coating that exposes graphite through the tin layer, enhancing stable sliding characteristics by retaining graphite particles during use.
Benefits of technology
The component achieves a low friction coefficient and stable sliding performance from the initial stage, with the tin coating retaining graphite particles and reducing friction fluctuations.
