Problems solved by technology

The existing anodic oxidation technology is mostly used on crystalline metals and alloys, and there is no report on the application of zirconium-based amorphous alloys.
Moreover, the preparation of highly ordered nanotube arrays on crystalline zirconium and zirconium alloys often requires the use of a secondary anodic oxidation method: first, a layer of irregular nanotube arrays is prepared on crystalline zirconium and zirconium alloys using anodic oxidation technology. Ultrasound and other means are used to remove irregular nanotubes, anodize again, and finally obtain a highly ordered nanotube array layer, which increases the complexity of the processing process

Description

technical field [0001] The invention relates to a method for modifying the surface of zirconium-based amorphous alloys, in particular to a method for preparing highly ordered oxide nanotube arrays on the surface of zirconium-based amorphous alloys. Background technique [0002] Due to its unique structure of long-range disorder and short-range order, amorphous alloys have relatively high mechanical properties such as strength, hardness, and wear resistance, and have always been a research hotspot in the field of material science. Zirconium-based amorphous alloy system has high amorphous forming ability, excellent mechanical, electrochemical and forming ability, and has a wide range of theoretical and practical application values. And because the metal element zirconium has very high biocompatibility, therefore, zirconium-based amorphous alloys have great potential for application as biomedical alloys. However, the surface of zirconium-based amorphous alloys appears to be bi...
