Effect of APS Arc Current and Hydrogen Flow Rate on the Structure and Mechanical Properties of Gd2Zr2O7 Topcoats in a Multilayer YSZ/GZO Thermal Barrier System
Thermal barrier coatings protect metallic components operating under severe high-temperature conditions, but conventional yttria-stabilized zirconia (YSZ) coatings face limitations at elevated temperatures. Gadolinium zirconate (Gd2Zr2O7, GZO) is a promising alternative topcoat material; however, controlling its porosi...
