ABSTRACT:
A high temperature flame spray or plasma effects thermal spray impact of molten materials against a target area of a surface to be built up, which molten particles, when cooled, are in tension, and an impact fusion internal burner device producing a supersonic jet stream impacts thermal spray heated solid particles against the surface in the target area such that the high velocity of the individual solid particles are impact fused, causing compressive stresses to be set up in the fused solid particles. The individual particle tensile and compressive stresses cancel one another to form an overall essentially stress-free coating. The flame spray molten particles and the flame spray heated solid particles may impact the surface concurrently at a same impact point. Alternatively, thin separate layers of the molten particles and the heated solid particles are deposited on the surface to be built up and superimposed on each other such that the tensile and compressive stresses of the particles of respective superimposed layers cancel each other out.
