ZrO2 38Y2O3 Powder Description:
ZrO2 38Y2O3 Powder is a yttrium-stabilized zirconium oxide material with a high content of yttria, created through agglomeration and plasma densification. This material is specifically engineered to improve the performance of thermal barrier coatings (TBCs) by enhancing their resistance to degradation from CMAS (Calcium Magnesia Alumina Silicate) attacks, which are common at surface temperatures above 1250°C (2280°F). Coatings made from ZrO2 38Y2O3 Powder demonstrate excellent high-temperature properties, lower thermal conductivity compared to conventional 7-8 wt.% yttria-stabilized zirconium (YSZ) materials, and superior thermal shock resistance when used as a top layer over standard YSZ TBC systems. Additionally, these coatings have a thermal expansion coefficient similar to traditional TBC systems and can be applied using atmospheric plasma spray techniques.
