Embodiment Construction

[0012] The substantive characteristics and remarkable effects of the present invention are further illustrated below through the introduction of the embodiments. But in no way limit the invention.

[0013] The titanium coating was prepared by vacuum plasma spraying technology. The prepared titanium coating was immersed in 5M NaOH solution and kept at 60°C for 24 hours. After taking it out, it was ultrasonically cleaned with deionized water for 3 times, each time for 5 minutes, and then immersed in deionized water. , kept at 40°C for 48h, then dried at 40°C for 24h, and the dried sample was heat-treated at 600°C for 1h. The heat-treated samples were immersed in a supersaturated calcium phosphate solution, kept at 25°C for 48 hours, and taken out to dry naturally. The preparation method of supersaturated calcium phosphate solution is as follows: Weigh 8.300g NaCl, 0.4162g CaCl 2 , 0.3423g K 2 HPO 4 ·3H 2 O was put into 1000ml deionized water, and the pH value of the solutio...

Abstract

The present invention relates to an activation method for the generation of apatite on the surface of a titanium coating. The chemical processing method of the surface of the titanium coating includes the following four steps: alkali solution soaking, deionized water soaking, heat processing and pre-calcification in supersaturated calcium phosphate solution. The vacuum plasma spraying method is adopted to deposit titanium powder on a washed and sandblasted metallic substrate in order to form the titanium coating, and the metallic substrate adopts titanium alloy, CoCrMo alloy or stainless steel. A simulated body fluid soaking experiment shows that the coating modified by the method has excellent bioactivity, and in the simulated body fluid, an apatite layer can be rapidly induced to form on the surface of the titanium coating in one day.

Description

technical field [0001] The invention relates to an activation method for rapidly generating apatite on the surface of a titanium coating, more precisely, to a method for preparing a biologically active titanium coating capable of rapidly inducing the formation of an apatite layer on the surface of a metal implant, belonging to medical biological Coating field. Background technique [0002] Titanium alloys, CoCrMo, stainless steel and other metals or alloys have excellent mechanical strength and processing properties, and are widely used clinical bone implant materials. However, since metal materials do not have living activity, their combination with bone tissue is mainly fixed by simple physical form. [0003] In order to improve the combination with bone tissue, metal implants need to increase the surface roughness to enhance their mechanical fit with bone tissue. The more common method of surface roughening is to prepare a titanium coating on the surface of the implant ...
