Plasma spray processes: diagnostics and control?

M. Vardelle, P. Fauchais
1999 Pure and Applied Chemistry  
The expenses related to the rejection and replacement of imperfect coatings can reach 15% of the production cost. Thus, for manufacturers, the reproducibility and reliability of plasma sprayed coatings are the main goals for respecting quality standards and decreasing production cost. The aim of this paper is a tentative to answer to the questions: ÐWhich diagnostics can be used within harsh conditions prevailing in spray-booths? ÐWhich close-loop control can be achieved between the on-line
