Collision Behavior of Molten Metal Droplet by Laser Beam

레이저 빔에 의해 생성된 금속액적의 충돌거동

A molten metal droplets are deposited onto solid substrate for solid freeform fabrication, Collision dynamic and substrate heat transfer associated with solidification determine the final shape of molten metal droplets. In this study, the experimental model, based on the variational condition with substrate temperature and falling height, was produced reliable optimal data of droplet pattern.
