Abstract

The invention relates to a preparation method of a biodegradable magnesium alloy / calcium phosphate coating composite material. The preparation method comprises the steps of pre-treating a matrix, preparing a conversion liquid, and preparing a bionic calcium phosphate coating to obtain the biodegradable magnesium alloy / calcium phosphate coating composite material. Compared with the prior art, the preparation method has the advantages that the prepared ZK60 magnesium alloy / calcium phosphate coating composite material can be used for remarkably improving the corrosion resistance of a ZK60 magnesium alloy, greatly reducing the degradation rate of the ZK60 magnesium alloy in a bionic body liquid and promoting the research and application of the ZK60 magnesium alloy in the medical field.

Description

technical field

[0001] The invention relates to a preparation method of a biomedical degradable material, in particular to a preparation method of a biodegradable magnesium alloy / calcium phosphorus coating composite material. Background technique

[0002] Biomedical degradable materials are mainly used for diagnosing, treating, repairing or replacing damaged tissues and organs of organisms, and improving their functions. In recent years, research on medical magnesium and magnesium alloy materials has gradually become a research hotspot in the field of biomaterials. As a typical representative of degradable biomaterials, magnesium and magnesium alloy materials are called "revolutionary metal materials". and has attracted widespread attention domestically. Compared with other kinds of biological materials, the development of biomedical metal materials appears to be relatively slow in recent years. However, metal materials have the advantages of high strength, fatigue resista...
