Abstract
A two-step process for coating magnesium and its alloys is disclosed. The first step comprises immersing the magnesium in an aqueous solution comprising about 0.2 to 5 molar ammonium fluoride at a temperature of about 40 to 100 DEG C. The second step is an electrochemical treatment in an aqueous electrolytic solution having a pH of at least about 12.5 and which solution comprises about 2 to 12 g/L of a soluble hydroxide, about 2 to 15 g/L of a fluoride-containing composition, and about 5 to 30 g/L of an alkali metal silicate.
