Powder Development and Qualification for High-Performance Cold Spray Copper Coatings on Steel Substrates

This paper presents the development work undertaken to tailor Cu powder size specifications to produce dense cold spray Cu coatings featuring strong adherence on steel substrates. Through review of historical data generated in the course of the development of Cu coatings for corrosion protection of Used (Nuclear) Fuel Containers, it was found that particle size distribution was particularly critical to meet application adhesion requirements of...
