隐身复合层及其制备方法
By forming grooves on the surface of the diffusion barrier layer and embedding a stealth layer to create visible light extinction grooves, the problems of easy diffusion and high visible light reflectivity of noble metal coatings in high-temperature environments are solved, achieving a stealth effect that is compatible with both visible light and infrared at high temperatures.

AI Technical Summary
Existing precious metal coatings are prone to diffusion failure in high-temperature environments and have high reflectivity in the visible light band, which affects stealth performance and makes it difficult to meet the requirements of visible light and infrared compatible stealth in high-temperature environments.
A diffusion barrier layer with grooves on its surface is used, a stealth layer is embedded and a visible light extinction groove is formed on its surface, and a noble metal material is combined to form a stealth composite layer. The diffusion barrier layer is prepared by anodizing and grooves are formed on its surface, and the stealth layer is embedded to form a visible light extinction groove.
The bonding force between the stealth layer and the diffusion barrier layer has been improved, avoiding high-temperature diffusion failure and achieving stealth performance in both visible and infrared bands under high-temperature environments.
