Five densities of laser-ablated micro-pits were fabricated onto medium-carbon steel surfaces based on the coupling effect of the biological surface. The effects of the surface textures on the wear behavior were investigated by sliding wear tests under starved lubrication. The results show that compared with the smooth sample, the biomimetic samples could effectively reduce friction and wear, and the tribological performance of the textured surfaces is closely related to the density of the bionic units. The equivalent stress distribution of the specimens was simulated by the finite element method. A uniform stress distribution is beneficial for effectively reducing the generation of wear cracks.

Effects of shot-peening on Cr-Rare earth-boronizing at 650°C for 4 – 8h for medium carbon steel are investigated in this paper. The value difference in boron diffusion activation energy between shot-peening and undeformation is calculated. The layer depth, microhardness and brittleness are also analyzed. The results show that the activation energy has a decrease of 5647.78 J/mol after shot-peening for 1.5h, and the layer depth increases with prolonged shot-peening time. The layer can also retain its high hardness with low brittleness. The analysis indicates that shot-peening can provide a large number of crystal lattice defects that facilitates boron diffusion in the steel, and the low temperature is apt to remain high dislocation density.
