Description

technical field [0001] The invention relates to a 3D printing method and equipment for high frequency induction heating assisted cold spray deposition metal. Background technique [0002] The forming method of cold spray deposition parts originated from cold spray technology (Cold Gas Dynamic Spray, CGDS), which was developed in the middle and late 1980s by A.N.Papyrin, a researcher at the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the former Soviet Academy of Sciences, and his colleagues. When conducting supersonic wind tunnel experiments with tracer particles, it was found that when the speed exceeds a certain critical value, the tracer particles will be deposited on the surface of the target. They proposed the concept of cold spraying in 1990 and published the first paper on cold spraying. Thesis and application for the first patent on cold spraying. [0003] Specifically, the cold spray technology is to enter the high-pressure gas (nitrogen...
