摘要: The effect of surface structure and coating on tribological properties 45# carbon steel disc was analyzed. A Nd:YAG laser used to generate microdimples surfaces. Dimples with diameter 150 m depth 50 were distributed in an orbicular array surface. Then the alloying element Mo sputtered by means double glow plasma technology. Diffusion layer 30 min thickness high hardness up 0.025 formed Tribological experiments three types samples (smooth, texturing texturing+alloying) conducted a pin-on-disc tribometer. It is found that dimpled-samples are most effective for reducing friction comparison smooth surfaces, improving lubricating state from boundary hydrodynamic region.
