The company is one of the few enterprises in China that have mastered the manufacturing technology of cold spraying additives and realized industrial application in the field of aircraft maintenance and remanufacturing. Mainly engaged in customized additive manufacturing and airborne equipment maintenance.
Since its establishment, the company has been focusing on the maintenance of aviation equipment, mainly engaged in the maintenance of pneumatic accessories, hydraulic accessories, fuel accessories and electrical accessories of military and civil aircraft. At the same time, after years of research and innovation, the company has carried out customized design of production line, construction of raw material supply chain and raw material quality inspection system, preparation and modification of metal powder, and research and development of cold spraying process parameters. ? And the adaptability of the substrate. ? The high-strength deposition of various metal materials has been realized, and the company's cold spraying additive manufacturing technology system has been established, and this technology has been successfully applied to the field of body structure remanufacturing.
Cold spray additive manufacturing technology is a coating preparation method based on high-speed particle solid deposition. The ejected particles collide with a solid substrate and undergo severe plastic deformation to deposit and form a coating. Cold spraying additive manufacturing technology has no thermal effect on the matrix, and can be used as near-net forming technology to directly spray to prepare blocks and parts. It has broad application prospects in the preparation of protective coatings and functional coatings, equipment manufacturing and remanufacturing. ? At present, cold spraying additive manufacturing technology has been applied to the maintenance and remanufacturing of military equipment such as helicopters, fighters, bombers and submarines in developed countries and regions such as the United States, Europe and Australia.
