Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China Building Materials Federation. This standard is under the jurisdiction of the National Industrial Ceramics Standardization Technical Committee (SAC/TC194). Drafting organizations of this standard. China Building Materials Inspection and Certification Group Co., Ltd., Shenzhen 863 New Material Technology Co., Ltd., Anhui Linghu Paint Co., Ltd., Zhengzhou Zhongben Refractory Technology Co., Ltd., China Building Materials Research Institute Co., Ltd., China National Building Materials Inspection and Certification Group (Shaanxi) Co., Ltd., Shandong Industrial Ceramics Research and Design Institute Co., Ltd.

Test method for high temperature elastic modulus of ceramic thick coating

1 Scope

This standard specifies the terms and definitions, principles, and instrument design for testing the elastic modulus of ceramic thick coatings using the pulse excitation method at high temperatures. Preparation, samples, tests, results and calculations and test reports. This standard applies to the test of the elastic modulus of ceramic thick coatings on metal substrates or ceramic substrates below 1500°C.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document. JC/T 2172 Fine ceramics elastic modulus, shear modulus and Poisson's ratio test method pulse excitation method

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Thickcoating Coatings with thickness greater than 30μm. 3.2 Thickness ratio The ratio of the thickness of the coating to the thickness of the substrate. 3.3 Composites The whole formed by the coating and the substrate.

4 Principle

For a thick ceramic coating with a continuous interface and tightly bonded to the substrate, its elastic modulus can be calculated by the pulse excitation method and related formulas. The elastic modulus of the coating is obtained by three parameters, namely the elastic modulus (Es) of the matrix sample, the elastic modulus (Eq) of the composite sample, the coating and The thickness ratio of the substrate (R=h/H). The values of Eq and Es are measured by the high-temperature pulse excitation method.

5 Equipment

5.1 Elastic modulus tester A pulse excitation test system that should meet the requirements of JC/T 2172 and can be used in a high temperature environment. ......
