ZR5971 Zirconium Dioxide Yttrium Oxide Composite Powder (ZrO2 48Y2O3 Powder)

ZrO2 48Y2O3 Powder Description:

ZrO2 48Y2O3 Powder is a zirconium dioxide material with a high Yttrium oxide content (48 wt.%), specifically developed for top coats in thermal barrier coatings (TBCs). This powder is engineered to produce dense or segmented microstructures when applied via atmospheric plasma spray technology, offering significant advantages over conventional 7-8 wt.% Yttrium oxide-stabilised zirconium dioxide. The high Yttrium oxide content results in low thermal conductivity and excellent phase stability at high temperatures, thereby extending the lifespan of the coating. Additionally, ZrO2 48Y2O3 Powder provides improved resistance against molten sand and ash (CMAS), although it may exhibit lower erosion resistance compared to materials with lower Yttrium oxide content. The molten and pulverised manufacturing process of the powder produces coatings with very low porosity, making it suitable as a top coat in conjunction with intermediate layers of 7-8 wt.% Yttrium oxide-stabilised zirconium dioxide and MCrAlY bond coats in multilayer or graded TBC systems for industrial gas turbines and aerospace engines.
