Dry Sliding Wear Test on Borided AISI 1018 Steel Under Pin-on-Disc Configuration

Abstract

New results about the influence of a small iron borided layer (~36 lm) obtained by the powder-pack boriding process (PPBP) and diffusion annealing post-process (DAP) were evaluated. Dry sliding wear tests on PPBP, PPBP + DAP and untreated AISI 1018 steel were performed under the pin-on-disc configuration, and balls of Al 2 O 3 and WC were used as a counterpart at different sliding distances. Also, the contact pressures of the layer/substrate system were evaluated using the finite element model with the aid of the ABAQUS software. The results showed that the Al 2 O 3 ball presented the major coupling (ball-disc), and the PPBP + DAP reduces the specific wear rate around ~304 times related to the untreated AISI 1018 steel to 500 m under severe sliding conditions.

Wear and corrosion resistance of Al2O3 and TiC deposition on steel substrate using self- propagating high temperature synthesis method

“…The higher hardness of the TiC annealed specimen makes it resistant to wear at extreme conditions and aids in the formation of tribolayer and MML formation as observed on the worn surface (figure 10(c)). The elemental composition of the disc counterpart, substrate, and oxides on the worn surface were all related to the tribo-oxidation wear as observed in borided AISI 1018 and AISI 316L steel respectively [56,57]. The oxide layer is formed by the wear debris from the disc and coating and is scraped off during subsequent wear.…”
