ZR5986 ZrO2 38Y2O3 Powder

ZrO2 38Y2O3 Powder Description:

ZrO2 38Y2O3 Powder is a yttrium-stabilized zirconium oxide material with a high yttria content, produced through agglomeration and plasma densification. This material is specifically designed to enhance the performance of thermal barrier coatings (TBCs) by increasing their resistance to degradation from CMAS (Calcium Magnesia Alumina Silicate) attack, which is common at surface temperatures above 1250°C (2280°F). Coatings made from ZrO2 38Y2O3 Powder exhibit 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 comparable thermal expansion coefficient to traditional TBC systems and can be applied using atmospheric plasma spray techniques.
