This study was aimed to investigate the effect of the substrate preheating temperature on the overall quality of the coating/substrate interface. The coatings (stainless steel) were deposited using a water stabilized plasma torch (Institute of Plasma Physics, Prague, i.e. IPP, Czech Republic) on steel substrates. Three sets of samples were prepared under identical spraying and grit blasting condition; substrate preheating temperature was the only parameter which was varied, i.e. preheating to 150°C, 250°C and 350°C. Higher preheating temperature led to a significant increase in the coating adhesion.
