Abstract

Atmospheric plasma spraying was employed to deposit Zirconia/Alumina (ZrO2/Al2O3) and Zirconia/Alumina-Titania (ZrO2/Al2O3-TiO2) multilayer coatings with bonding material (Ni-Cr-Al) on the EN31 Mild Steel substrate. The investigation was carried out on multilayer ceramic coated specimen by thermal torch and shock test methods. The coated specimens were prepared as per ASTM standards. Micro structural analysis was carried out using scanning electron microscope to investigate the thermal resistance of the two different multilayer ceramic coatings. The results show that the multi-layered ZrO2/Al2O3 coating possesses improved thermal properties when compared to ZrO2/Al2O3-TiO2 multilayer coating.
