Description
Technical Field
The invention belongs to the technical field of application of titanium alloy in the ocean, and particularly relates to a preparation method of marine microorganism corrosion resistant titanium alloy.
Background
The titanium alloy has excellent performances of low density, high strength, seawater corrosion resistance and the like, is widely applied to equipment such as ships, pressure-resistant shells, heat exchangers, seawater desalination devices, coolers, condensers, pipelines and the like, and is known as ocean metal in the ocean engineering fields such as ocean thermoelectric power generation, oil gas exploitation, aquaculture and the like. However, the titanium alloy has good biocompatibility, is an ideal habitat for marine organisms, and the life activities of the marine organisms can generate certain corrosive metabolites, so that the interface state of titanium/seawater and the properties of a medium are changed, the microbial corrosion is caused, the stability of a protective oxide film or coating on the surface of a metal is damaged, and pitting or crevice corrosion is further caused, so that the application environment of the titanium alloy is deteriorated. Meanwhile, due to the adhesion and propagation of microorganisms, organic matters, sediment and other inorganic matters in seawater are easily adhered to the mucus secreted by the microorganisms, the thickness is gradually increased, the running resistance of equipment is increased, if the microorganisms exist on the inner wall, the flow is reduced, and under the action of turbulent flow, the oxidation film on the inner surface is continuously flushed by the seawater, so that the titanium tube is thinned, and finally broken to form large-size perforations. Therefore, how to improve the marine microorganism corrosion resistance of titanium alloys and reduce the attachment fouling of organisms is a problem which needs to be solved in marine engineering applications.
Common methods for preventing microbial corrosion include chemical, physical and biological methods. Wherein the chemical method comprises killing spores or larvae by selecting effective chemical substances, or generating a solution containing cuprous oxide and Al (OH) by electrolysis of seawater electrolyte 3 Effective chlorine, killing or inhibiting the growth of microorganism to achieve the aim of corrosion prevention. The physical method mainly utilizes ionizing rays (including ultraviolet rays, gamma rays and X rays) or ultrasonic treatment to kill or remove microorganisms attached to the surface of the titanium alloy. Biological methods utilize symbiotic, competing, and antagonistic relationships between microorganisms to prevent corrosion of metals by the microorganisms. The method can weaken the corrosion of marine microorganisms to the titanium alloy in a short period of time, but has the advantages of short service cycle and complex process,high cost, ecological environment destruction and the like. If the titanium alloy material resistant to marine organism corrosion can be developed, the structural and functional integration is realized, and the marine organism corrosion problem which exists for a long time can be solved with low cost and environmental protection.

In order to solve the problems, the technical scheme of the invention is as follows:

The design basis of the invention is as follows:
in an etching medium, two metals of different potentials can form a galvanic cell, and the corrosion of a metal in contact with another metal of higher potential is called galvanic corrosion. The standard electrode potentials of the titanium and the rare earth element have larger difference, when the titanium and the rare earth element are in solution, a couple is formed, the couple corrosion occurs, the rare earth element with low potential is corroded in an accelerating way, and the titanium with high potential is protected. Meanwhile, the growth and adhesion of marine organisms on the surface of the titanium alloy are effectively inhibited by utilizing the antibacterial effect of rare earth element ions, and the rare earth element ions are further oxidized to form a compact oxide film on the surface of the titanium alloy.
Wherein, the added rare earth element has lower electrode potential than titanium, and the rare earth element preferentially corrodes in the process of forming a primary cell, thereby playing a role in protecting titanium. The added rare earth element has the function of sterilizing or inhibiting the growth of bacteria. The added rare earth element oxide has high stability, and can promote the formation of a compact oxide film on the surface of the titanium alloy.
Compared with the prior art, the invention has the following advantages:
1. the invention utilizes an alloying method to prepare the marine organism corrosion resistant titanium alloy, and effectively overcomes the complexity and high cost of a coating method, a chemical method or a physical method.
2. According to the invention, the difference between the added element and the standard electrode potential of the titanium element is directly utilized, a primary cell is formed in the alloy to improve the corrosion resistance of the titanium alloy, and rare earth element ions subjected to oxidation reaction play a role in inhibiting biological growth.
3. The rare earth elements added in the invention are beneficial to promoting the formation of passivation films on the surface of the titanium alloy, and further improving the corrosion resistance of the titanium alloy.
