Embodiment 1

[0050] Choose Ta with a particle size of about 10 μm 2 o 5 Powder (w(Ta 2 o 5 )=99.99%) as raw material (purchased from Jiujiang Fengfu New Material Co., Ltd.), made into slurry with 40% solid content for spray granulation, atomizer speed: 22,000 rpm, feed rate: 770ML / points, the obtained powder morphology is as follows figure 1 shown. Depend on figure 1 It can be seen that most of the powder is in the shape of spherical particles with uniform size, about 20-80 μm, and has good fluidity. The powder was dried at 110°C for 1 hour, and cooled for later use.

[0051] The base material is made of titanium sheet, which is processed into a small disc of Φ10mm×2mm. After sandblasting the surface of the titanium sheet, ultrasonically clean it once in absolute ethanol solution for 3 minutes, then dry it at 100°C for 1 hour, and cool it for later use; the pressure of sandblasting is 0.3MPa.

[0052] Atmospheric plasma vacuum plasma spraying process is used respectively to spray ...

Abstract

The invention relates to a tantalum oxide coating both having good biocompatibility and photothermal conversion effects and a preparation method and application of the tantalum oxide coating. The tantalum oxide coating is formed by spraying Ta2O5 powder by adopting a plasma spraying method. The tantalum oxide coating has higher bone differentiation facilitating capacity, good biocompatibility andthe photothermal conversion performance.

Description

technical field [0001] The invention relates to a tantalum oxide coating with good biocompatibility and light-to-heat conversion effect, its preparation method and application. Specifically, it relates to a tantalum oxide coating sprayed by plasma spraying technology and a preparation method thereof, belonging to the technical field of medical biological coatings. Background technique [0002] Due to population aging, bone tumors, bone deformities, and traffic accidents, metal bone implant materials have been widely used clinically, such as titanium total joint replacement materials. Tantalum has good corrosion resistance and the function of promoting bone regeneration, and it has attracted widespread attention as a bone implant material. [0003] Tantalum has good biocompatibility, and the dense natural oxide layer on the surface of tantalum metal plays an important role. This layer of natural oxide layer is more stable than titanium oxide, and the presence of tantalum ox...
