| Abstract | Dimpled textures were prepared by using a pulse solid laser on the surface of Al-Si alloy. The combination of laser surface texturing (LST) andMoS2 solid lubricant as well as their tribo logical properties were investigated in this article. The obtained friction and wear data were critically analyzed to investigate how the parameters of texture influence the tribological perfor mance of Al-Si alloy. Furthermore, morphological investiga tions of the transfer layers on the worn surfaces were performed and the wear mechanisms are discussed. The results show tha the combination of LST and solid lubricant improves the tri bological characteristics of Al-Si alloy. The friction coefficien of Al-Si alloy steel friction pairs can be reduced to 0.15 under dry friction. The lubricationmechanismis attributed to a syner getic effect of providing solid lubricant and traps wear debris in the dimples. It was found that the optimum density of structure was 37%for excellent tribological properties. |
