  • Acousto-immersion coating and process for magnesium and its alloy
    Patent number: 6669997
    Abstract: A process for coating an object formed of magnesium or a magnesium alloy comprising the steps of: immersion coating the object in a sonicated bath to form an undercoat and topcoating the object to form a topcoat. When desirable to protect against topcoat failure, the undercoat may be equally noble or more noble than the topcoat. If topcoat failure is not a concern, the nobility of the topcoat relative to the undercoat need not be considered. The process promotes uniform coating of a magnesium and its alloys.
