Analysis of Ta/Ni Multilayer Cold Spray Coatings

Abstract

Characterization was completed on two multi-layered cold spray coatings. The samples consisted of flat steel substrates coated with ~820 microns of Ni and a topcoat of ~210 microns Ta deposited via cold spray. Characterization was completed to determine thickness, structure, and adhesion of the coatings. To determine coating thickness and structure metallographic analysis was completed. Adhesion was analyzed via groove adhesion testing. Further analysis to determine constituents of cold spray coatings was completed via SEM-EDS.
