Abstract

The invention aims to provide a titanium alloy nano-coating with an antibacterial function and a preparation method thereof. The titanium alloy nano-coating is characterized by comprising the following chemical components of, by mass percent, 2-10% of Cu, 0.04-0.1% of Ce and the balance Ti, wherein the preferable range of the chemical components reaches the following standards that the Cu accountsfor 4-8%, the Ce accounts for 0.06-0.08%, and the balance is the Ti. According to the preparation method of the titanium alloy nano-coating, a titanium-copper-cerium nano-coating with the antibacterial function is formed on the surface of a substrate, so that the substrate can obtain a coating with the broad spectrum and the antibacterial function; and the coating has the excellent corrosion resistance in a biological medium and a corrosive solution.

Description

technical field

[0001] The invention belongs to the technical field of depositing medical nano-coatings on the surface of metal materials, and specifically provides a titanium alloy nano-coating with antibacterial function and a preparation method thereof. Background technique

[0002] In the current medical field, the problem of bacterial infection caused by metal medical device implants has become more and more important. According to statistics, the annual incidence of orthopedic implant-related infections in the United States reaches about 4.3%. According to the relevant data in the "Practical Handbook of Nosocomial Infection Prevention and Control" promulgated by the World Health Organization (WHO), more than 14 million people in the world suffer from nosocomial infections every day, and 60% of bacterial infections are related to the medical devices used. Bacterial infections caused by medical devices can have disastrous consequences for patients once they occur. Pati...
