Since work temperature is relatively low (always lower than melting temperature), it is ideally for depositing temperaturesensitive materials such as nanophased and amorphous materials or oxygen-sensitive materials. Material cost reduction (raw materials, gases ...), reduction of surface treatments (pre- and post-spraying), possibility of increasing the pieces life, reduction of the problems associated with material melting (oxidation, corrosion, residual tensile stress ...), maintenance of the starting microstructures, etc., have made that cold spray technique an efficient, more ecological and economically more affordable than conventional spraying and deposition techniques.
