METHOD FOR ANODISING MAGNESIUM AND MAGNESIUM ALLOY COMPONENTS OR ELEMENTS

摘要

The invention comprises a method for anodising magnesium or magnesium alloy components or elements, comprising or including the steps of: (1) providing an aqueous electrolytic solution consisting of an alkali or alkali earth metal hydroxide, and aluminate salt and a phosphate which is not a monophosphate, where the electrolyte solution does not contain ammonia of chromate or fluoride species; (2) providing an inert cathode in the solution; (3) providing a magnesium or magnesium alloy anode in the solution; and (4) passing a current between the anode and cathode through the solution, to deposit a film on the magnesium or magnesium alloy anode. Further, products of the method of the invention are claimed.
