Description
Technical field
The invention belongs to the technical fields of the anti-sea organism attachment of titanium metal material, and in particular to persistently protect in a kind of seawater
Titanium-based metal surface copper/aluminium MULTILAYER COMPOSITE anode and its application.
Background technique
Titanium alloy has low-density, and the excellent performance such as high-intensitive and seawater corrosion resistance is widely used in ocean thermal gradients
Power generation, sea water desalination, oil-gas mining, naval vessel, the ocean engineering fields such as aquaculture are described as " marine metal " by people.Titanium closes
Fitting has good biocompatibility, is the ideal habitat of marine growth, therefore, biodeterioration of the titanium alloy in ocean engineering
Problem is more more serious than other metal materials.The attachment of marine growth will increase ship resistance, make the energy consumption and discharge of ship
Aggravation.The energy of attachment of marine growth accelerates the structural members such as marine facility, building to be stained corrosion, significantly shortens its service life.It is reported according to the U.S.
Road, due to the attachment of marine growth, the U.S. causes 50~6,000,000,000 dollars of loss every year.In face of the serious harm of marine growth, people
Have studied many methods for preventing marine growth adhesion reduction to be stained.Studies have shown that copper ion and cuprous oxide are able to suppress Hai Sheng
The attachment of object.Be primarily due to: copper product becomes copper ion by the effect with seawater, and copper ion can reduce main in living organism
The activation of enzyme, to shorten bio-longevity.Further study showed that the leaching rate when copper is greater than 10 μ g/ (cm2It can when d)
Inhibit barnacle attachment；When the leaching rate of copper is greater than 10~20 μ g/ (cm2D) hydra, jellyfish attachment be can inhibit；When copper ion
Leaching rate is greater than 20~40 μ g/ (cm2D) it can inhibit algae attachment；When the leaching rate of copper ion is greater than 40 μ g/ (cm2D) may be used
Prevent that bacterium adheres to；When copper ion leaching rate is greater than 50 μ g/ (cm2When d), it can inhibit most sea organism attachments.
Therefore, the attachment that can effectively inhibit marine growth by the leaching rate of control titanium alloy copper ion in the seawater, works as copper ion
Leaching rate be greater than 50 μ g/ (cm2When d), so that it may inhibit most sea organism attachments.It is different in the seawater using titanium and copper
Corrosion potential, can accelerate the corrosion of copper product using the principle of galvanic corrosion, obtain needed for inhibiting sea organism attachment
The copper ion concentration wanted.
This difference using copper and titanium corrosion potential in the seawater, realizes that the method for the accelerated corrosion of copper can be effective
Inhibition marine growth in the attachment on titanium surface, also effectively applied in practical projects.But it is found in practice in engineering, with
The generation of copper surface corrosion product, this layer of corrosion product inhibit further corroding for copper, make the precipitation concentration of copper ion by
It gradually reduces, reduces the effect for inhibiting sea organism attachment.
Summary of the invention
Technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, provide in a kind of seawater to hold
Continuous protection titanium-based metal surface copper/aluminium MULTILAYER COMPOSITE anode.The copper/aluminium MULTILAYER COMPOSITE anode structure is simple, can be realized
The copper ion of concentration is precipitated in the even many decades sustained release height into seawater that lasts for several years, and restrained effectively the attached of marine organisms
, extend the service life in the seawater of titanium-based metal.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: titanium-based metal surface is persistently protected in seawater
With copper/aluminium MULTILAYER COMPOSITE anode, which is characterized in that including being stacked alternately layers of copper and aluminium layer together, the thickness of the layers of copper

Show) when, since there are potential differences for titanium and copper, they form galvanic couple, and galvanic corrosion just has occurred, and the low copper of current potential is accelerated
Corrosion, while copper is corroded, copper surface also deposited corrosion product (as shown in Figure 3), since corrosion product is in loose shape,
Also no galvanic corrosion (as shown in Figure 4) does not occur for the copper of corrosion and the corrosion product on copper surface and the aluminium being exposed, due to aluminium
Corrosion potential is lower, accelerates the corrosion of bottom aluminium, cracking to be eroded completely due to the very thin thickness of aluminium layer, makes copper
And the corrosion product on copper surface, to be stripped from anode surface, is gone back without the basis of anode surface is attached at this point, exposing
The next layers of copper that do not corrode, this provides fresh anode for galvanic corrosion further occurs with titanium, enables copper ion
Lasting generation.
Compared with the prior art, the present invention has the following advantages:
Copper of the invention/aluminium MULTILAYER COMPOSITE anode construction is simple, and layers of copper and aluminium layer stack gradually, and the thickness of layers of copper
Degree is 40 μm~180 μm, aluminium layer with a thickness of 5 μm~7 μm, copper of the invention/aluminium MULTILAYER COMPOSITE anode and titanium-based metal are connected
It being connected together and is placed in seawater, galvanic corrosion occurs for copper and titanium, copper ion is discharged, and produce cuprous oxide, once layers of copper is worn
Thoroughly, aluminium layer exposes, then also no galvanic corrosion does not occur for the copper of corrosion and the corrosion product on copper surface and the aluminium being exposed, by
It is thin in aluminum layer thickness, it is easy to which that fast erosion is complete, so that the layers of copper and corrosion product being located above aluminium layer is fallen off, new layers of copper weight
It is new to expose, galvanic corrosion occurs with titanium, is continued for discharging copper ion to the side of titanium-based metal, and the copper ion discharged
Leaching rate is greater than 50 μ g/ (cm2D), the ability of the sustainable release copper ion is up to several years or even many decades, during being somebody's turn to do
It can be effectively prevented the surface that marine organisms are attached to titanium-based metal, extend titanium-based metal and use the longevity used in the ocean
Life.
