Abstract:This paper is devoted to the presentation of our actual knowledge in plasma spraying. It presents successively: the parameters controlling the impact of the molten particles onto the substrate and resulting splat formation followed by splats layering and coating formation; the engineering of nano- or finely structured coatings with different possible routes; and the actual possibilities for the on-line control of the spray process.
Keywords: plasma spraying; suspension plasma spraying; plasma torches; particle flattening; splats; coating formation.
*Paper based on a presentation at the 16th International Symposium on Plasma Chemistry (ISPC-16), Taormina, Italy, 22-27 June 2003. Other presentations are published in this issue, pp. 345-495.
