Abstract
A study was undertaken of four iron and two cobalt based hard facing alloys as GMA cored wire surfaced to evaluate quantitatively their low-stress abrasion resistance as a function of chemical composition and hardness. ASTM G 65 Procedure A was used as the method of abrasion resistance evaluation. The most important variable in determining low-stress abrasion resistance was found to be chemical composition (microstructure) of the deposit. One and three layer deposits of high chromium cast iron and cobalt alloy based alloys have shown highest abrasion resistance, over 2.5 times higher than HARDOX 400 steel. Hardness has secondary effect on abrasion resistance and cannot be use as the abrasion resistance indicator. Dilution has an important effect on abrasion resistance of iron-based alloys.
