Abstract
Technology for microplasma spraying of coatings provides a small size of the spraying spot (several millimetres), is characterised by small dimensions of the equipment involved, and a low level of noise. Microplasmatron with a special wire feed device was designed to use wire as a source material for spraying. Structure and properties of coatings produced by the microplasma method using Mo, W, Ti, Ni–Cr, Al, brass and steel wire were investigated. The investigation results prove the possibility of applying this method for production of dense coatings with a spraying spot ranging from 3 to 8 mm
Keywords: microplasma spraying, plasmatron, wire feed mechanism, wire spraying, wire materials, copper, tungsten, coating, microstructure
