Abstract

Yttria stabilized Zirconia (YSZ) coatings are used as thermal barrier coatings in airspace and gas turbine industries. In this study, the application of zirconia coatings stabilized with 8% weight, ytteria is investigated using the electrophoretic deposition(EPD) method in a solution containing acetone and ethanol with a volume fraction of 3 to 1 on the substrate of Inconel 738 low carbon alloy. The present article studied the effect of process parameters of sintering temperature, surface roughness, and adhesion. Also, the coating structure was studied using X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). The results showed that the coated samples' hardness, adhesion, and surface roughness were determined after sintering at 900, 1050, and 1200 OC for 2 and 4 hours. As the temperature increases, the hardness and stickiness of the sample increase, and the surface roughness decreases. This increase in the hardness and adhesion of the coating surface at the sintering temperature of 1200 OC and in a period of 4 hours is more than 2 hours.
