Powder can be spread onto a tray and then solidified in the required pattern with a squirt of a liquid binder or by sintering it with a laser or an electron beam.
Single pass laser surface of the specimens using powder feeding method were obtained by varying the powder feeding rate and the preheating temperature of the substrate.
通过改变送粉激光熔覆过程中的扫描速度、送粉速率、基体预热温度等工艺参数，获得了单道激光熔覆层。
