Abstract
A new type of martensite stainless steel deposit electrodes was developed. The welding technicality of the electrodes was analyzed, and the wear resistance of the deposited metal was studied through a slurry abrasive wear test. The results indicated that the welding arc of the electrodes could keep steady during welding process, and the appearance of weld and the detachability were satisfied. The microstructure of the hardfacing alloy consisted of lath martensite and fine strengthening phase with dispersive distribution. The mass loss of hardfacing alloy was about one third of that of substrate, which means the hardfacing alloy has a good wear resistance property. And the main wear mechanisms are micro-cutting, micro-ploughing and the second wear of plastic deformed metals.
