AbstractThe abrasion properties of a series of hardfacing deposits of chromium carbide alloys and tungsten carbide composites have been examined using the laboratory pin test. Corrt;lation between the abrasion resistance and variation in microstructural parameters of the deposited layers was determined for both 120 j1m garnet and 80 j1m alumina abrasives. The effects of alloy hardness (Hv) and volume fraction of primary carbide (Vc) on abrasion characteristics are shown to depend in a critical manner on abrasive type.
