3 Terms and definitions
The following terms and definitions apply to this document:
3:1
Ceramiccoating
A ceramic coating layer that is coated on the surface of various substrate materials using physical or chemical processes:
3:2
Maximumtensileload
In the tensile bonding strength test of the coating, the maximum load is applied perpendicular to the coating-substrate interface to the maximum load that the coating and the substrate peel off:
3:3
Tensile bonding strength of cladding
The ratio of the maximum tensile load to the peeling area of the coating from the substrate:
3:4
Maximumshearload
In the coating shear bond strength test, the maximum load that is applied parallel to the coating-substrate interface to the peeling of the coating and the substrate:
3:5
Cladding shear bonding strength
The ratio of the maximum shear load to the peeling area of the coating from the substrate:
4 Test principle
Place the cross-bonded sample in a special fixture in two different ways and apply a load to it to make the coating test strip and the butt bar
