Scope
Scope: This document specifies the technical requirements, quality assurance, marking, packaging, transportation, storage, and quality certificates for thermal barrier coating powder materials used in plasma physical vapor deposition (PVD). This document applies to thermal barrier coating powder materials for PVD applications; Main technical content: 4.1 Product Classification: The products may include conventional 8YSZ, RE-YSZ, GdYbZrO, and ultra-high temperature thermal barrier coating materials Gd2Zr2O7. 4.2 Chemical Composition: 4.2.1 Binder Content in Powder: The binder in the powder should enhance the cohesion and compression strength of the powder, and the binder content should be (1~2)wt.%. 4.2.2 Chemical Composition of Powder: The chemical composition of conventional 8YSZ thermal barrier coating powder materials is shown in Table 1, the chemical composition of multi-element rare earth oxide-doped modified YSZ (RE-YSZ) thermal barrier coating powder materials is shown in Table 2, and the chemical composition of ultra-high temperature thermal barrier coating powder materials is shown in Table 3. The binder content is not included.
