Micro Cold Spray Direct Writing of Patterned Thick Films

Micro Cold spray allows the deposition of patterned thick films by high velocity impact of solid sub-micron particles onto polymer, metal, or ceramic substrates. The particles deform upon impact, creating high density films at room temperature. Since ceramic and metallic films can be deposited at room temperature, it is possible to produce hybrid ceramic and metal devices on temperature-sensitive substrates. We are studying the deformation and film formation mechanisms when metal and ceramic particles are exposed to extremely high strain rates that are typical for this process. Projects are supported by the Army Research Laboratory, L3-Harris Corp, and Los Alamos National Laboratory.
