T/CIET 1685-2025 Surface ceramic material technology specification for thermal barrier coating
Basic Information
Scope
This document specifies the common types of materials for surface ceramic layers in thermal barrier coating systems, their physical and chemical performance requirements, test methods, quality inspection and qualification criteria, as well as marking, packaging, transportation, and storage. This document is applicable to thermal barrier ceramic layer materials prepared by processes such as plasma spraying (APS) and electron beam physical vapor deposition (EB-PVD).
