Abstract
The invention discloses a method preventing marine organisms from adhering to the surface of titanium or titanium alloy. The method comprises the steps that titanium material and copper material are closely placed in an attached mode so as to obtain a galvanic corrosion structure, and then the galvanic corrosion structure is placed in seawater; the ratio of the surface area of the part, immersed into the seawater, of the titanium material in the galvanic corrosion structure to the surface area of the part, immersed into the seawater, of the copper material in the galvanic corrosion structure is 1-100 to 1, wherein the titanium material is commercial pure titanium, and the copper material is commercial pure copper or copper alloy. According to the invention, the titanium material and the copper material generate galvanic corrosion in the seawater, so that corrosion of the copper material is accelerated and a lot of copper ions and cuprous oxide are generated, the copper ions and the cuprous oxide are spread to the surface of the adjacent titanium material, and therefore the marine organisms can be prevented from adhering to the surface of the titanium material.
Description
Technical field
The invention belongs to the applied technical field of titanium material in ocean, be specifically related to a kind of method preventing titanium or titanium alloy surface attachment marine life.
Background technology
The difficult problem that marine settings runs in process is under arms the attachment of marine life and stained problem.Various marine organisms, as barnacle, algae, oyster, mussel, lime worm, Enteromorpha etc. can ship housing, marine structure, aquaculture net cage etc. on the surface non-selectivity big area adhere to.The adhesion of marine life can increase hull bottom roughness, causes ship resistance to increase, and the energy consumption of boats and ships is aggravated with discharge, brings high risks to ship's navigation.According to statistics, shell stained 5% under waterline, fuel by increasing consumption 10%, stained 10%, fuel, by increasing consumption 20%, is stainedly greater than 50%, and fuel is by increasing consumption more than 40%.The adhesion of marine life can accelerate the stained corrosion of the structural part such as maritime facilities, building, significantly shortens its life-span.The fouling organism of these adhesions can cause pH value, oxyty and other solvency concentration spatially skewness in its adhering zone, thus changes speed and the process of metallic material corrosion.Fouling organism also can accelerate process and the speed of galvanic corrosion.It is reported, due to the Anaerobic Corrosion that sea marine organism pollution causes, the U.S. causes the loss of 50 ~ 6,000,000,000 dollars every year.In the face of the serious harm of marine life, people have studied many marine lifes that prevents and adhere, and reduce stained method.
Antifouling paint is one adopted method very early, stanniferous coating poisonous in early days gradually replace by Tin-free Spc Anti-fouling Paint, as Red copper oxide (Cu
2o) stain control agent, heterocyclic sterilization, mould inhibitor etc.The construction of brushing antifouling paint is complicated, and the life-span is short.Anti-fouling electrolyze sea water has life-span long, the hypochlorite ion that generates to advantages such as sea pollution are few compared with antifouling paint method, but complex structure, need additional electrolysis power, to not having, the environment of electric energy is inapplicable.People are found by the phenomenal research of " be positioned over copper product surface in seawater and or less can not have sea organism attachment ", and cupric ion and Red copper oxide can suppress the attachment of marine life.Copper product is by becoming cupric ion with the reaction of seawater, and cupric ion can reduce the activation of apoenzyme in living organism, to shorten bio-longevity.Red copper oxide can kill larva and the spore of marine life.Research shows, when the rate of release of copper is greater than 10 μ g/ (cm further again
2d) barnacle can be suppressed time to adhere to; When the rate of release of copper is greater than 10 ~ 20 μ g/ (cm
2d) hydra, jellyfish attachment can be suppressed; When the rate of release of cupric ion is greater than 20 ~ 40 μ g/ (cm
2d) algae can be suppressed to adhere to; When the rate of release of cupric ion is greater than 40 μ g/ (cm
2d) bacterial adhesion can be prevented; When cupric ion rate of release is greater than 50 μ g/ (cm
2d), time, most sea organism attachment can be suppressed.Therefore, the attachment of marine life can just effectively be suppressed by the rate of release controlling Copper Sea Waters ion, when the rate of release of cupric ion is greater than 50 μ g/ (cm
2d), time, just most sea organism attachment can be suppressed.According to these research, be developed electrolytic copper-aluminium (iron) antifouling and electrolytic chlorine-copper, aluminium anti-fouling method, generated containing Red copper oxide, Al (OH) by the electrolysis of seawater electrolysis matter
3, available chlorine, reach the object preventing sea organism attachment, equally, these two kinds of method complex structures, need electric energy.
Titanium alloy has low density, the performance that high strength and seawater corrosion resistance etc. are excellent, is widely used in ocean thermal energy conversion, sea water desaltination, oil-gas mining, naval vessel, the oceanographic engineering fields such as aquaculture, is described as " marine metal " by people.Titanium alloy has good biocompatibility, and be the desirable habitat of marine life, therefore, the biodeterioration problem of titanium alloy in oceanographic engineering is more serious than other metallic substance.
