Metal and other inorganic coatings Test method for thermal cycle and thermal shock performance of thermal barrier coatings1 ScopeThis document describes two test methods for thermal barrier coatings, using a steady-state cyclic heating and cooling method to test the thermal cycle resistance, and using a heated Thermal shock resistance is tested by heat and chill methods. This document is used to evaluate the durability of thermal barrier coatings under thermal strain. This document is suitable for screening thermal barrier coating systems including materials and processing techniques, and is not suitable for controlling thermal spraying processes.2 Normative referencesThe contents of the following documents constitute the essential provisions of this document through normative references in the text. Among them, dated references For documents, only the version corresponding to the date is applicable to this document; for undated reference documents, the latest version (including all amendments) is applicable to this document. ISO 14232 Thermal spraying powder composition and supply technical conditions (Thermalspraying-Powders-Composition Note. GB/T 19356-2003 Thermal spraying powder composition and technical supply conditions (ISO 14232.2000, MOD) strength) Note. GB/T 8642-2002 Determination of thermal spray tensile bond strength (ISO 14916.1999, MOD)3 Terms and DefinitionsThe following terms and definitions apply to this document. 3.1 A two-layer structural coating consisting of a metal bond layer and an oxide ceramic topcoat designed to reduce heat transfer from the ceramic topcoat to the substrate. NOTE. Thermally grown oxide (TGO) will develop on top of the bond coat when the thermal barrier coating is in service at high temperatures. Typical substrate materials are nickel-based superalloys material. As shown in Figure 1, the preparation method adopts physical vapor deposition, chemical vapor deposition or thermal spraying process, such as plasma spraying and high-velocity flame coating. Flame spraying (HVOF), the spraying powder material complies with the provisions of the corresponding part of ISO 14232. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 42259-2022_English be delivered?Answer: Upon your order, we will start to translate GB/T 42259-2022_English as soon as possible, and keep you informed of the progress.
