Anticorrosion Conversion Coating Content Lanthanum and Phosphate on Foam Mg Alloy
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.
