Abstract
The invention discloses a magnesium alloy silver-containing micro-arc oxidation electrolyte, a biological ceramic membrane layer and a preparation method. The electrolyte is composed of the followingcomponents of, Na5P3O10 with the concentration being 5-15 g / L, NaOH with the concentration being 1-3 g / L, C3H8O3 with the concentration being 5-15 ml / L, CH3COOAg with the concentration being 1-3 g / L,NaF with the concentration being 0.5-5.5 g / L, n-Hap with the concentration being 0.5-10.5 g / L and K2TiF6 with the concentration being 0.5-10.5 g / L. The phase of a prepared ceramic membrane layer comprises MgF2, Mg3(PO4)2, TiO2, Ag2O, Mg2PO4(OH) and Ca7Sr3(PO4)6(OH)2. The ceramic membrane layer has good corrosion resistance, biocompatibility, good bonding property with a matrix and good antibacterial property.
Description
technical field [0001] The invention belongs to the field of magnesium alloy surface treatment, in particular to a magnesium alloy silver-containing micro-arc oxidation electrolyte, a bioceramic film layer and a preparation method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Magnesium alloy has many excellent properties, such as high strength and specific stiffness, good shock absorption and electromagnetic shielding performance, easy cutting and recycling, and rich storage capacity, making magnesium alloy as the lightest industrial material widely used in electronics, aerospace and the automotive field. Magnesium is a very active metal with poor corrosion resistance...
