The Influence of Tungsten on the Pitting of Aluminum Films

Year: 1990

Type: article

Abstract: Many of the alloying additions responsible for the corrosion resistance of stainless steels can also be used to enhance the passivity of aluminum, provided that these lements remain in solid solution in the alloy. Passivity enhancing elements uch as Cr, Mo, Ta, Zr, and W typically exhibit very low solubility limits in aluminum, below 1 atomic percent, and at these con-centrations exert little influence on corrosion behavior. However, these solubility limits can be increased with a concomitant enhancement i corrosion performance if the alloys are produced using a rapid solidification process. One such process is co-sputter deposition of two metals, such as A1 and W, simultaneously to form a binary alloy of W in solid solution with AI. Co-sputter deposition is routinely used to produce compound
