摘要:
A method for producing a corrosion-inhibiting coating on an implant made of a biocorrodible magnesium alloy, the method comprising providing the implant; and treating the implant surface using an aqueous or alcoholic conversion solution containing one or more ions selected from the group consisting of K+, Na+, NH4+, Ca2+, Mg2+, Zn2+, Ti4+, Zr4+, Ce3+, Ce4+, PO43−, HPO42−, H2PO4−, OH−, B33−, B4O72−, SiO32−, MnO42−, MnO4−, VO3−, WO42−, MoO42−, TiO32−, Se2−, ZrO32−, and NbO4−, wherein the concentration of the ion or ions is in the range of from 0.01 mol/l to 2 mol/l. An implant produced by this method is also disclosed.
