Abstract
A thermal spray alloy system is disclosed that is more resistant to corrosion and wear than conventional thermally sprayed coatings. The alloy system utilizes layers of different alloys to provide increased wear and corrosion resistance. The disclosed alloy addresses issues of wear and corrosion by utilizing a copper-based alloy as one thermally sprayed layer and an iron-based alloy as a second thermally sprayed layer via twin wire arc spray application processes, as is known in the art. The first layer may be about 50.0 wt % to about 95.0 wt % of copper. Between 2-10 applications of each layer may be applied to a substrate.
