Cold spray is a solid-state powder-based materials deposition technology that uses highly pressurized gas to deposit materials on substrates at ambient temperatures and pressures, and at very high deposition rates. Such low temperature solid state manufacturing processes provide notable benefits such as maintaining powder feedstock phase purity, and elimination of segregation and solidification shrinkage effects. In this study, the deposition of chromium coatings on zirconium-alloy light water reactor (LWR) fuel cladding, and ensuing properties and microstructure of the coatings have been investigated. The coatings have very good hydrothermal corrosion resistance as well as oxidation resistance in air and steam environments at temperatures in excess of 1100C, the prevailing environment under loss of coolant accident conditions. These results, along with measurements of residual stress state and micromechanical tests to understand the deformation behavior of cold spray Cr coatings, will be presented.
