... is that the quality of cold-sprayed deposits depends on the ratio of v p to v cr ; for example, the tensile strength of the cold-sprayed coating increases linearly with increasing η = v p / v cr ( Ref 3.5 ). Therefore, to ensure successful and optimized cold spraying, the influence of various process...
