Abstract

Wear of plasma-sprayed TiO 2 coating against stainless steel was tested with a block-on-ring arrangement at different loads and sliding speeds. It was found that wear mass loss of TiO 2 coating increased with increase in loads but decreased with increase in sliding speeds. The mechanism was explained in terms of grinding wear, adhesive wear, micromechanical delamination wear, plastic deformation wear, melting wear and formation of Fe 2O 3Fe 3O 4 thin film.
