| Abstract: |
| As a new type of material whose performance changes with composition or structure, functional gradient materials are increasingly being applied to improve the tribological properties of mechanical components. In order to study the anti-wear and friction reduction effect of functional gradient materials on the surface of cylinder liners, a regular texture arrangement with a 30° angle was prepared on the surface of cylinder liners to explore the coupling effect of material and texture on the improvement of tribological properties. |
