Abstract : Coatings deposited by ion plating are becoming more widely used for corrosion protection. Aluminum coatings may be the most advanced commercially at this time. Other identified candidates (depending upon the substrate) are iron-chromium, aluminum-magnesium, copper-aluminum, and titanium-nitride. Important characteristics of these coatings are chemical composition and microstructure. An amorphous or microcrystalline structure can result in vastly enhanced resistance to corrosion for metal films that have an inherent tendency toward passivity. These structures can also lead to the formation of a resistant spinel-type oxide layer in certain alloys. The influence of process parameters in achieving these structures is discussed.
