Texture Evolution of Nickel Coatings Fabricated by Aerosol Deposition

Abstract

In order to understand the evolution of texture during the aerosol deposition (AD) method, coatings were deposited under various conditions using pure nickel powder particles. These particles are thought to undergo plastic deformation during deposition. X-ray diffraction analyses of the surfaces of the coatings obtained revealed specific textures. A {101} fiber texture was observed in as-deposited specimens. Texture development was observed with increasing gas flow rate. The strain in the nickel coating was estimated to be about 1.0–1.4 in true strain. This strain is thought to be induced by the nickel particles impacting the substrate during deposition.
