Abstract

A new ‘satelliting’ preparation method was used to create a feedstock of pure Al powder to which a much finer TiC powder was attached. Cold spray (CS) coatings of pure Al, blended Al/TiC and satellited Al/TiC were applied to Al substrates. A seven-fold increase in TiC area fraction was measured in the satellited coating compared to that in the blended coating. Coating thickness also increased as a result of increased ceramic deposition. Cross-sectional analysis revealed that the cohesion achieved between Al and TiC, during satelliting process, survives the CS process, and is hence an effective method of producing ceramic-metal coatings.
