Abstract

Cold Spray (CS) technology enables structural reinforcement, coating and repairing of metal-based components. The deposition occurs by the impact of small particles accelerated at supersonic velocity on the deposition surface. While processing stainless steel material the CS must be run in high-pressure conditions, thus making any in-situ repairing prohibitive and risky. This paper presents a novel CS deposition method to coat stainless steel with a compact and transportable system infrastructure. The final part of the paper shows the advantages of the proposed CS deposition system against existing methods, in relation to industrial coating applications.
