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.
