Description

technical field [0001] The invention relates to a vacuum ion-plated Ag nanocomposite coating fastener and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] High-strength fasteners used in aerospace and other special fields are generally made of stainless steel, titanium alloys, and high-temperature alloys. The surface requires not only excellent wear resistance, but also good lubrication and corrosion resistance. Silver and silver-based coatings have good lubricating properties in high and low temperature and vacuum environments, and are widely used coating materials in fasteners. Silver plating has methods such as electroplating, chemical plating, and vapor deposition, among which electroplating is the most widely used. The widespread use of electroplating silver began in 1800. The first patent for silver plating was proposed by the Elkington brothers in Birmingham, England in 1838. The gold system is very simil...
