A Fundamental Understanding of the Effect of Alloying Elements on the Corrosion Resistance of Rapidly Solidified Mg Alloys.
Abstract
During the first year of this project progress was made in areas that bear on the effect of alloying elements on the corrosion resistance of RSP magnesium alloys, theory of alloying constituents, EXAFS determination of structure of oxide or hydroxide films, and electrochemical evaluation of corrosion resistance. The theoretical studies aided in the selection of constituents of alloying elements for binary alloys used in the complimentary Lockheed AFWAL project (Aluminum, Calcium, Zinc, Lithium, Phosphorus, Chromium). They suggested that elements that promote hydrogen bonding in hydroxide films, Al, Zn, or Boron, should be beneficial. Silicon which produces a surface protective Silicon dioxide shows promise as a alloying element.
