Beschreibung
Zusammenfassung:	The invention discloses an anti-nitrogen high-temperature-resistant coating and a preparation method and application thereof.The anti-nitrogen high-temperature-resistant coating comprises a single silver plating layer or a combination of the silver plating layer and a hydrophobic layer, the silver plating layer is located on the surface of a base body, the hydrophobic layer is arranged on the surface of the silver plating layer, and the hydrophobic layer has high temperature resistance and hydrophobic performance. When the composite coating containing the silver plating layer and the hydrophobic layer is prepared, the silver plating layer is formed on the surface of a substrate through electroplating or chemical plating, and then the hydrophobic layer is formed in a spraying mode. The material can be applied to aero-engine parts, is low in preparation cost, can greatly improve the anti-nitriding performance, has high temperature resistance, and prolongs the service life of the parts. 本发明公开了一种防渗氮耐高温涂层及其制备方法和应用
