Abstract

In many industrial applications components are subjected to erosive wear caused by fluid flow. Wear resistant coatings may be applied to increase the component life time. When the coating fails the wear rate usually increases rapidly, resulting in a fast deterioration of the performance of the component. In case the coating wear could be monitored such that the coating failure could be detected early enough to prevent wear of the substrate material, recoating of the component could be possible and feasible. In this report modes of erosion, methods for erosion testing, erosive wear of coatings and possible methods for monitoring the coating wear particularly under slurry erosion are reviewed on the basis of literature.
