The heating of the substrate by the jet may influence on the process of coating deposition by DYMET technology. It can be observed as deposition efficiency variation at various nozzle transverse speeds. Experimental investigation of the deposition efficiency variation for different jet stagnation temperatures and different substrate thermal properties is presented and discussed. The suppression of substrate influence on the deposition process with the coating thickness growth is demonstrated.
