Slurry Erosion Resistance of Cr_3C_2-Ni Cermets

摘要

Chromium carbide based cermets, due to their high corrosion resistance, are perspective material to use in corrosive and abrasive environments. Present paper covers slurry erosion corrosive wear properties of chromium carbide based cermets with different chemical compositions (10-40% of Ni). Widely used WC-Co cermets are used as reference material. Erosion corrosion wear in case of distilled water and distilled water plus abrasive are investigated. It is shown that chromium carbide based cermets exhibited superior wear resistance compared to WC-Co cermets. Wear mechanism was investigated by SEM images of worn surfaces.
