Zusammenfassung:The invention relates to a laser forming method of a TiC-Al-Gr composite material component. According to the formula, the raw material powder selected and used in the method comprises, by weight percentage, 5.67%-6.35% of graphite, 40.54%-44.43% of Ti, 0.47%-0.67% of mischmetal and the balance Al. The powder formed through lasers is quantitatively conveyed through a multi-hopper conveying system, a three-pipe coaxial laser head is adopted for laser forming, and an inside-outside gradient delamination structure of the TiC-Al-Gr component can be achieved by controlling the powder conveying system and the laser head, and the fracture toughness of the TiC-Al-Gr component can reach over 60% of the Al alloy.
