ZR5986 Zirconium Dioxide Yttrium Oxide Composite Powder (ZrO2 38Y2O3 Powder)

ZrO2 38Y2O3 Powder Description:

ZrO2 38Y2O3 Powder is a Yttrium-stabilised zirconium oxide material with high Yttrium content, produced through agglomeration and plasma densification. This material was specifically developed to enhance the performance of thermal barrier coatings (TBC) by increasing their resistance to CMAS attacks (Calcium-Magnesia-Alumina-Silicate), which frequently occur at surface temperatures above 1,250°C (2,280°F). Coatings made from ZrO2 38Y2O3 Powder exhibit excellent high-temperature properties, lower thermal conductivity compared to conventional 7-8 wt.% Yttrium-stabilised zirconium (YSZ) materials, and superior thermal cycling resistance when used as a top coat over standard YSZ-TBC systems. Additionally, these coatings possess a comparable thermal expansion coefficient to conventional TBC systems and can be applied using atmospheric plasma spraying techniques.
