Abstract

S-phase layers on austenitic stainless steels have demonstrated significantly enhanced wear and corrosion properties. Most of the tribocorrosion work on S-phase was conducted against an alumina or tungsten carbide counterpart. However, no work has been done on thecorrosion-wear behaviour of a tribopair both made from Sphase layers. However, S-phase against S-phase is both scientifically and technologically important since the S-phase can have commercial applications in the food and biomedical industries where there is a need of metal-on-metal sliding. In this work AISI 316 balls and discs were plasma surface alloyed with nitrogen and carbon to form S-phase layers and their corrosion-wear behaviour was tested in a 0.15M NaCl solution using a reciprocating wear tester. The results demonstrate that the S-phase tribopair can produce a markedly decrease in material lost when compared to an untreated tribopair.
