This paper discusses on the effect of welding conditions on wear phenomena of low manganese deposited steels and on the effect of heat treatment on the improvement of wear resistance of the deposited steel.
The results showed that the wear mechanism and the curve representing the relation between sliding velocity and wear characteristics were nearly identical with those results obtained by low carbon deposited steels.
However, the relation between the number of deposited layers and the wear showed that the wear loss was likely to be decreased with the increase in the number of layers, depending upon the behavior of alloying elements.
Moreover, the treatment of quenching or tempering after the welding was very effective in improving wear resistance of the deposited metal. In particular, the tempering at 200°C after quenching was the most suitable condition of heat treatment for the decrease of wear loss.
