[0002] Cold spray technology is a deposition technology based on aerodynamics. Cold spray technology has many advantages, such as low spraying temperature, strong coating adhesion, uniform and dense, less oxides, and good electrical and thermal conductivity. This makes cold spraying have broad application prospects in the fields of chemical industry, automobile, aerospace, shipbuilding, electronics, machinery, papermaking, etc. It can be used to produce and repair turbine blades, pistons, bearings, cylinders, valves and other parts. In addition, cold spray technology also has important applications in the biomedical field, such as the preparation of metal coatings, polymer coatings, ceramic coatings and antibacterial coatings. When performing cold spraying, a cold spray powder material supply device is required to assist;

When the powder material is used for cold spraying, the final spraying effect will be poor, and there is a certain probability that the powder material supply device for cold spraying will be blocked internally, which is inconvenient. Therefore, we propose a powder material supply device for cold spraying. Utility Model Content
