What is it about?
This manuscript highlights the resistance to two-body and three-body abrasive wear of iron and nickel based composite hardfacings with ex-situ added Cr3C2-Ni reinforcement, which were manufactured by submerged arc welding (SAW), plasma transferred arc (PTA) welding and tungsten inert gas (TIG; otherwise called GTAW) welding.

Why is it important?
This study allows to compare the suitability of different welding technologies for manufacturing of composite overlays (hardfacings) with Cr3C2-Ni reinforcement. More specifically, it shows that overall TIG welding is the most optimal technology for manufacture of such hardfacings.
Perspectives
This manuscript should ease the choice of a hardfacing technology for those, who have to deal with the improvement of machine parts' resistance to abrasive wear and who consider hardfacings as a possible solution.
