Abstract

The invention discloses a micro-arc oxidation electrolyte, a micro-arc oxidation film layer as well as a preparation method and application of the micro-arc oxidation film layer. The micro-arc oxidation electrolyte is composed of the following components of 5-15 g / L of NA5P3O10, 1-3 g / L of NaOH, 5-15 ml / L of C3H8O3 and an additive, wherein the additive is a mixture of at least two kinds of n-Hap,Na2WO4, NaF and a fluorotitanate, the fluorotitanate is potassium fluotitanate or ammonium hexafluorotitanate, and n-HAp is hydroxyapatite. The additive n-HAp participates in the micro-arc oxidation reaction and can obviously improve the performance of a coating, and the addition of n-HAp improves the bonding strength of the micro-arc oxidation coating and a base body, helps the self-healing of micropores in the coating and enhances the corrosion resistance of a sample.

Description

technical field [0001] The invention belongs to the technical field of magnesium alloy surface treatment, and in particular relates to a micro-arc oxidation electrolyte, a micro-arc oxidation film layer and a preparation method and application thereof. 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 to be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In recent years, magnesium alloys have received extensive attention as biomedical degradable implant materials. Magnesium alloy density and Young's modulus (1.74-1.84g / cm 3 ,41-45GPa) are closer to natural bone tissue (1.8-2.1g / cm 3 ,15-25GPa), which can effectively alleviate the stress shielding effect. Magnesium is involved in almost all metabolic processes of th...
