Abstract
Reducing wear on mechanical components that have a metal-metal sliding contact has always been a challenge in the study of tribology. In this context, thermochemical treatments are an effective option to improve surface mechanical properties and prolong the life of mechanisms subjected to wear, corrosion and abrasion. In this study, the resistance to adhesive wears of layers of iron boride generated on the surface of AISI 316L steel was evaluated experimentally and numerically. The borurization treatment in AISI 316L steel was carried out by the pack-boriding process at different time and temperature conditions. The tribological behavior of the layer-substrate system was estimated by performing wear tests, with the configuration rotatory pin on disk, without lubricant and using an Al2O3 ball. Experimental results showed that the borurization treatment significantly improved the wear resistance of AISI 316L steel compared to the untreated material. The wear depth was estimated by Archard’s linear wear law. It was found that the results of the numerical model by means of finite element method are consistent with those obtained experimentally
