Abstract
Methods for applying grit containing abrasive coatings by plasma spray techniques are disclosed. Various concepts for obtaining good adherability of the coating to an underlying substrate and for maintaining angularity of the grit particles are discussed. The concepts employ simultaneous contact of the grit particles with matrix material at the surface of the substrate to be coated. In coating narrow substrates, the substrate is offset from the axis of the plasma stream discharging from the plasma gun.
