Production of High Quality Anti-Corrosion and Wear-Resistant Wire Arc Sprayed Coatings

Aim of this project is to produce anti-corrosion coatings for high temperature applications by wire arc spraying. It is necessary to adjust the feedstock material as well as the spray equipment in order to control the coating composition and the coating morphology. The substitution of expensive Ni- and Co-based feedstock by Fe-based alloys leads to an economic benefit. In combination with wire arc spraying, the total coating costs can be reduced significantly. There is also an enomous potential for reduction of service costs in waste incineration plants due to an enhanced coating service life and shorter downtime for the anti-corrosion coating repair.
