This work evaluates the potential of using twin wire arc (TWA) spraying as an alternative to metal active gas (MAG) overlay welding in the production of agricultural equipment. Corthal 65, a flux-cored wire electrode, was applied to different types of steel using each method. Some of the samples were tested in a lab and some were evaluated under actual use in the form of plow tips and harrow teeth. SEM and EDX analysis revealed the presence of Cr, Nb, and W carbides and Al-rich oxides in the hardfacing layer. Field-tested samples were assessed based on porosity and hardness, providing a measure of abrasive wear and impact resistance. The TWA-sprayed coatings performed as well as the MAG overlay welds, but their potential to improve productivity and reduce costs make them the more appealing option.
