Abstract

In this study; effects of plasma spray distance and Ar/H-2 gas mixture ratio on YSZ and CYSZ thermal barrier coating properties are investigated with the experiments and characterization studies. Within the scope of characterization studies; SEM analysis, porosity analysis with ASTM 2109 standard, adhesion strength tests compliance with ASTM C633 and also thermal shock tests were performed. The best thermal shock performance is observed in YSZ coated specimens which are produced from 75mm spray distance and it is 52 cycles. It was determined that, in this study, bonding strength of the coatings is between 4 and 10 MPa.
