Abstract
The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.
Claims15
A composite coating comprising:
- a polymer layer for covering a surface of a substrate, the polymer layer comprising a silicon-based polymer being a reaction product of triethoxymethylsilane and (3-mercaptopropyl)trimethoxysilane under a sol-gel process;
- a metal interlayer having a crystalline structure and covering the polymer layer;
- and
- an amorphous metal coating covering the metal interlayer such that the metal interlayer is sandwiched between the polymer layer and the amorphous metal coating.
