Xinova requires a few subject matter experts to opine on innovations around cold spray deposition/coating technologies. Our client has developed a low pressure cold spray technology that allows for deposition of thin films of metal powders. The company has investigated coating bus bars for high current connections for battery powered electric vehicles, and is now focusing on other commercialization opportunities for coating thin metal films onto existing substrates. They are also highly curious as to how other metallic/non-metallic powder/substrate combinations could be advantageous.
Background: Cold spray, referred to as supersonic particle deposition, is generally described as a high-energy solid-state coating and powder consolidation process. The cold spray process uses an electrically heated high-pressure carrier gas, like nitrogen or helium and other organic compounds, to accelerate metal powders through a supersonic de Laval nozzel above a critical velocity for particle adhesion.
The bonding mechanism is a mix of mechanical interlocking and metallurgical bonding from re-crystallization at highly strained particle interfaces.
Cold Spray can create mixtures of metallic and nonmetallic particulates to form a coating or freestanding structure by means of ballistic impingement upon a substrate. The process is applicable to corrosion-resistant coatings (zinc and aluminum), dimensional restoration and repair (nickel, stainless steel, titanium, and aluminum), wear-resistant coatings (chromium carbide – nickel chromium, tungsten carbide – cobalt, and tungsten copper), electromagnetic interference (EMI) shielding of components and structures, high strength dissimilar material coatings for unique manufacturing solutions, and field repair of components and systems.
