Abstract

The invention provides a preparing method of a medical metallic bone implant. Through preprocessing, sand blasting, anodizing, flame jetting and calcinating and forming, a tantalum / nanopore array Ta2O5 / hydroxyapatite material is obtained. The material is high in porosity, high in compressive strength and coating binding force and excellent in biocompatibility.

Description

technical field [0001] The invention relates to a preparation method of a medical metal bone implant material, and belongs to the technical field of medical metal bone implant materials. [0002] technical background [0003] Biomedical Jinli materials are widely used in the field of clinical medicine due to their excellent mechanical properties, ease of processing and stability. However, since this material is in direct contact with human tissue, it has high requirements for its design, preparation and surface modification, so that it can meet the physical and chemical properties different from ordinary materials and excellent biocompatibility. The selection criteria for biomedical materials are that they cause the least biological response in the body and can meet the basic functional requirements of the tissue to be replaced or repaired. Therefore, biomedical metal materials must meet the following basic requirements: ① Non-toxic: At present, the basic non-toxic metal ele...
