Abstract
Method of combination of a laser beam and plasma arc for realization of a combined process of a laser-plasma cladding is suggested. A prototype of a laser-arc plasmatron for a powder cladding was designed and manufactured. A detailed computer modelling of a combined discharge in the given plasmatron and experimental studies of its characteristics and technological capabilities of the mentioned process were made. It is shown that the combined use of a laser beam and plasma arc increases the speed, stability and reproducibility of results of cladding, and also efficiency of using these sources of heating.
Keywords: plasma arc, laser beam, combined discharge, laser-arc plasmatron, plasma-laser cladding, filler powder, investigations
