摘要

42CrMo steel is widely used in gears and bearings of large machinery. Enhancing its tribological properties is crucial for improving equipment reliability. This study employs hexagonal biomimetic texture as a foundation, designing three distinct shapes through topology optimization. By setting three texture densities, nine surface texture configurations were obtained. Specimens were prepared by filling solid lubricants SnAgCu and MAX phase material Mo2TiAlC2. Friction tests compared the nine groups with a texture-free sample. Results showed that the 30HE-D group exhibited a 15.3% reduction in average coefficient of friction and a 51.7% decrease in wear depth. The MAX phase material Mo2TiAlC2 added to the SnAgCu solid lubricant promoted its diffusion to form a lubricating film on the wear surface, demonstrating superior wear resistance.
