Abstract
A spraying material is fed to and melted in a high energy density zone formed by converging a laser beam therein with a converging lens or a mirror, and the molten spraying material is rendered into particles by jetting a carrier gas stream such that the axis thereof crosses the axis of the laser beam in the high energy density zone to blow the particles of the molten spraying material against a base surface disposed to be normal to the carrier gas stream axis beyond the high energy density zone so as to form a film of the spraying material on the surface.
