ZrO2 48Y2O3 Powder Description:
ZrO2 48Y2O3 Powder is a high-yttria zirconia material, containing 48 wt.% yttria, specifically designed for top coats in thermal barrier coatings (TBCs). This powder is engineered to produce dense or segmented microstructures when applied using atmospheric plasma spray technology, offering significant advantages over conventional 7-8 wt.% yttria-stabilized zirconia. Its high yttria content ensures low thermal conductivity and excellent phase stability at elevated temperatures, which extends the coating's service life.
Additionally, ZrO2 48Y2O3 Powder provides enhanced resistance to molten sand and ash (CMAS), although it may have lower erosion resistance compared to materials with lower yttria content. The powder's fused and crushed manufacturing process results in coatings with very low porosity, making it suitable for use as a top coat in combination with intermediate layers of 7-8 wt.% yttria-stabilized zirconia and MCrAlY bond coats in multi-layer or graded TBC systems for industrial gas turbines and aerospace engines.
