ABSTRACT:
A laser assisted thermal spray process for material spraying of a workpiece utilizes a primary energy source for producing a heating plume and a spray material injector for injecting a spray material comprising a plurality of particles into the heating plume. A deposit of the spray material transported by the heating plume is formed on the workpiece surface. The laser assisted thermal spray a process further utilizes a laser-heating system for irradiating a portion of the spray material and a portion of the targeted workpiece so as to limit incompletely melted particles thereon.
