Cold Spray Deposition entrains micron scale particles in supersonic gas to direct high-density deposition, but has typically been limited to ductile metals. Recently, we have demonstrated its extension to brittle functional materials, including hard and soft magnets. A range of feedstock powders can be sprayed onto substrates ranging from quartz to copper, and onto curved surfaces. The magnetic properties of the deposited material are governed by powder size and the gas velocity and temperature, formation of deleterious secondary phases can be suppressed by correct choice of processing conditions.
A summary of structural, compositional and magnetic characterization results will be presented, highlighting the flexibility and strengths of this manufacturing technique, and offering perspectives for future applications it will enable.
