Abstract : Salt spray tests were conducted with magnesiumsteel and magnesium-aluminum couples coated with alkyd and epoxy primers pigmented respectively with zinc chromate, strontium chromate, a mixture of zinc chromate and antimony oxide, and titanium dioxide. Results indicate that the optimum formulation for protecting the couples against corrosion is an epoxy-polyamide primer pigmented with the zinc chromate-antimony oxide mixture. Recommendation for the use of this coating is withheld pending the outcome of future work to determine its practicability as a primer for aircraft use. (Author)
