Zusammenfassung:The invention discloses a laser-assisted cold spraying method for manufacturing additives. The method comprises the following steps: preheating a base material by preheating laser to enable the temperature of the base material to be raised to 300-400 DEG C and lower than the melting point of the base material by at least 200 DEG C to obtain a preheated base material; performing additive accumulation on the preheated base material with a cold spraying technology, and performing surface treatment on cold sprayed coatings obtained by additive accumulation synchronously by synchronous laser. The accumulation combination effect of cold spraying additive manufacturing can be substantially improved, the accumulation coatings are not prone to falling off, accumulation efficiency is higher, flexibility is better, quality of the additives is substantially improved, and surface molding can be effectively controlled. 本发明公开了种激光辅助冷喷涂增材制造的方法,包括:采用预热激光对基材进行预热,使基材温度升温至300~400℃,并且低于基材熔点至少200℃,从而得到预热基材;采用冷喷涂技术对所述预热基材进行增材堆积,并采用同
