Abstract

The invention relates to a method for preparing arrayed TiO2 by catalytic oxidizing of pure Ti sodium tetraborate. A pure titanium rod is sliced and electrochemically polished, anhydrous sodium tetraborate fine powder is spread on a pure titanium slice which is then put into a crucible, and then the crucible is put into a muffle furnace to be heated up to 500-800 DEG C, heat is preserved for 3-7 h, and heating is stopped; and when the furnace temperature is reduced to the room temperature, the pure titanium slice is taken out of the aluminum oxide crucible, and arrayed TiO2 is obtained after cleaning. According to the method for preparing arrayed TiO2 by catalytic oxidizing of the pure Ti sodium tetraborate, the process is simple, the requirement for equipment is low, the prepared TiO2 is distributed in an arrayed shape evenly, after biological activating of the surface, high combining of a bioactive layer and a Ti substrate can be realized, and the problem of implanting failure caused by coating shedding of a Ti substrate implanting material during the implanting process is solved.

Description

technical field [0001] The invention relates to the technical field of preparation of nano-titanium oxide, in particular to the catalytic oxidation of pure Ti sodium tetraborate to prepare array-like TiO 2 Methods. Background technique [0002] Titanium and titanium alloys have become biomedical materials for bone tissue repair and replacement due to their excellent biocompatibility and mechanical adaptability. Titanium and its alloys are biologically inert materials in nature, and there is only a mechanical fit with bone, rather than a strong chemical osseointegration. In order to make its surface biologically active, people use many methods to modify its surface to prepare bioactive coatings to meet the requirements of organisms on the mechanical and biological properties of materials. In situ growth of TiO 2 The method to enhance the bonding strength of bioactive coatings and titanium substrates is a very effective method. Currently commonly used TiO 2 Coating method...
