Anticorrosion Conversion Coating Content Lanthanum and Phosphate on Foam Mg Alloy

Abstract

Foam magnesium alloy was an idea substitute of hard tissue of human bodies because its elasticity module was close to the bone of human. In the paper, foam degradable magnesium alloys were prepared by “Press-Dissolution-Vacuum sintering-Hot treatment-Aging” powder manufacturing process firstly. Then samples were coated by immersion in a bath containing phosphate and rare earths lanthanum. Results show that, Mg-0.9Mn foam magnesium alloys after hot treatment had better anticorrosion performance; and coated foam magnesium alloys form the bath with phosphate lanthanum chloride had lower rate of degradation.

Electroless Sn Deposition on Magnesium Alloy and Wastewater Treatment

“…The effective way to prevent magnesium from corrosion is to coat the base material. Hence more relevant studies have been done on formation of a rustproof coating on the surface of the magnesium alloy in recent years [3][4][5][6][7], which is necessary in practical utilization. Due to its excellent properties, electroless-deposition technique of Ni alloy coatings has been applied to a well-known commercial process in many fields [8].…”
