Abstract

The experiment for investigating the ejection angle of molten Aluminum induced by millisecond pulsed laser is designed. Two kinds of ejection modes are found from the experimental result. The molten droplets distribution of these ejection modes are in the shapes of sprinkled stars and circular ring, respectively. The mechanism of these different ejection modes are analyzed and discussed. The ranges of ejected droplets vary widely with the change of millisecond laser pulse energy. The droplets distribution in the circular ring shape becomes thinner with the increasing power density of pulsed laser. The ejection angle of major molten droplets dependence of pulsed laser power density is obtained from the experimental result. The influence of vaporization on the particle size and the distribution of ejected droplets are discussed.
