Abstract

The article presents the results of research on pad welds made using consumables in the process of metal active gas welding (MAG) combined with plasma arc welding (PAW). The pad weld consisted of a buffer layer and a wear-resistant working layer. Cerium, yttrium and lanthanum oxides were added to the powders to modify the working (active) layer. The HV10 hardness and friction coefficient testing was followed by measuring wear tracks and determining wear indicators (maximum wear track depth and area). Yttrium oxide was found to have a remarkably beneficial effect on nickel-based pad welds. In the case of iron-based welds, the most favourable outcome was observed for lanthanum oxide.
