"GB/T 45008-2024 Rare earth thermal barrier coating materials, gadolinium ytterbium zirconate powder" specifies the technical requirements, test methods, inspection rules and labels, Encasement, transportation and storage of gadolinium ytterbium zirconate powder. The standard applies to gadolinium ytterbium zirconate powder prepared by chemical method or high temperature solid-phase synthesis using ytterbium oxide, gadolinium oxide, zirconium oxide, etc. as raw materials, mainly used for thermal barrier coatings of high temperature components such as aero-engine blades and combustion chambers. Gadolinium ytterbium zirconate powder has excellent thermal insulation performance and thermal shock resistance, and is a key material for The implementation of the standard will help promote the industrialization of rare earth-based thermal barrier coatings in our country, break the blockade of foreign technologies, and meet the demand for high-performance thermal barrier coatings in the field of high-end equipment.
