Corrosive wear behaviour of Cr-Mn-Cu white cast irons in sand-water slurry media

摘要: Abstract An attempt has been made to develop Cr-Mn-Cu white cast irons for applications requiring corrosive and erosive wear resistance properties. Alloys with different compositions heat treatments were subjected tests under conditions. The relative index of each alloy after specific was evaluated respect standard nickel-hard type IV iron. corresponding test results indicate that the addition 3% copper Cr-Mn in ausaged condition markedly reduces (about 35%) loss saline slurry media. as-cast austenitic exhibits a better performance 43% 47%) than those hardened tempered or alloys, is comparable irons.
