    Abstract

    Corrosive wear phenomena are apparent in hydraulic machinery that handle slurries. This study focuses on the development of an integrated methodology of material assessment that is employed to understand the mechanisms of deterioration and effectively compare materials’ performance under impinging slurry. The technique involves mass loss measurements and post-test analysis of the surface, which comprises measurement of wear scar depths and volumes, that yield the quantification of the various material degradation processes that occur directly under, and adjacent to, the impinging jet. A medium carbon steel and a stainless steel have been investigated, since they exhibit different corrosive wear behaviour.
