Abstract
Cold gas dynamic spray technology, commonly referred to as cold spray, is well established in a number of industrial applications. Cold spray is used for corrosion protection with dense, pure low-oxygen zinc, aluminum, titanium or tantalum, as well as stainless steel and nickel coatings for dimensional restoration and repair. Cold spray technology is similar to thermal spraying, with the main difference that it does not melt or oxidize the powder feedstock. In cold spraying, velocities are increased even further and particle temperatures remain below the melting point. As a result, the cold spray coatings do not exhibit the detrimental effects associated with melting of the feedstock. Cold spray of materials such as copper and polymers offer innovative possibilities for cost-effective and environmentally friendly alternatives to technologies such as electroplating, soldering and painting.
