Abstract

Cold-spraying technology is a solid-state, powder-based coating deposition and additive manufacturing (AM) technology, which utilises a high-pressure gas stream to accelerate micron-sized particles through a de-Laval nozzle for supersonic speed and impact on substrates and to generate dense, high-quality deposits. Cold-spraying technology has many unique features (e.g., high deposition rate, high adhesion strength; solid-state bonding at low temperatures) contrary to other fusion-based techniques, thus opening up new opportunities in various industrial markets. After over thirty years of rapid development, cold-spraying technology has been successfully applied in surface repair, surface enhancement, functional coating, and AM in many fields, including the aerospace, weapon, energy and power, electronics, and medical equipment industries.
