Tribological and corrosion experiments of graphite ring against Ti–6Al–4V disk: Influence of electrochemical and mechanical parameters

Abstract

Friction of two materials in artificial seawater induces severe degradations of both antagonists. In view of evaluating materials wear resistance, this investigation is devoted to the development of a new ring-on-disk tribocorrosimeter device. Its relevance to the study of wear due to plan/plan friction is analyzed comparing it to classical pin-on-disk experiments, with special emphasis on the influence of several factors: choice and respective position of both materials in contact, applied load, test duration.
