Description
Technical field:
The present invention relates to a kind of method that prevents propeller for vessels corrosion and sea marine organism pollution.This method is applicable to the corrosion that prevents propeller for vessels and marine life stained the adhering on the screw propeller surface.Belong to marine corrosion and guard technology field.
Background technology:
Seawater is a kind of very strong Korrosionsmedium.Propeller for vessels adopts the Cu alloy material manufacturing usually, except the electrochemical corrosion that receives seawater, also can suffer destructions such as seawater scouring burn into cavitation corrosion in the course of the work, causes its surface damage, reduces its service life.Simultaneously, the screw propeller surface also is easy to produce sea marine organism pollution in seawater adheres to, and biofouling can influence the propulsion coefficient of screw propeller, and increases the underwater noise of screw propeller, and fouling organism also can cause copper alloy surface accelerated corrosion sometimes.Adopting corrosion resistant material is to prevent one of propeller for vessels corroding method, and as adopting titanium alloy etc., but it costs an arm and a leg, thereby copper alloy remains the most frequently used propeller material at present.In recent years, the someone has carried out the research of nonmetallic composite screw propeller, although have sea water corrosion resistant preferably, does not also get into actual application at present.Cathode protection also is one of effective ways that prevent the propeller for vessels corrosion, can in the protection hull, screw propeller be protected through adopting sacrificial anode or impressed current cathodic protection system.Although can alleviate marine corrosion, only depend on cathode protecting process can not solve the damage under the mechanics factor effect such as erosion corrosion and cavitation corrosion of screw propeller fully.In addition, more than these prevent that corroding method from all can not solve the sea marine organism pollution problem, and owing to after the screw propeller surface is protected, do not corrode like copper alloy surface, then its surface forms sea marine organism pollution more easily and adheres to.For often resting on the harbour, the boats and ships that duration of voyage is less, the problem of its screw propeller sea marine organism pollution can show more seriously.Also once had the people to solve the corrosion and the stained problem of screw propeller at screw propeller surface coating organic anti-corrosive coating and antifouling paint, but the organic paints coating is easy to destroy, used life is imitated short, and permanently effective protection can not be provided.
Summary of the invention:
The objective of the invention is to the anticorrosion and existing deficiency of anti-fouling method, a kind of long-acting method that can prevent propeller erosion and sea marine organism pollution simultaneously is provided to above-mentioned existing ship screw propeller.The inventive method adopts the combination of cathode protection, insulating ceramic coating and metal nonpolluting coating, can realize the anticorrosion and antifouling of propeller for vessels.Adopt this method can effectively solve the corrosion and the sea marine organism pollution problem of propeller for vessels, and the long life protection is provided.
In order to realize the foregoing invention purpose; Propeller for vessels antiseptic and antifouling method of the present invention is on copper alloy screw propeller matrix, to adopt heat spraying method to prepare the metal oxide ceramic insulating coating earlier; Prepare the metal nonpolluting coating then above that, simultaneously screw propeller is implemented cathode protection.
The ceramic insulation interlayer has high hardness and excellent anti-erosion corrosion performance; Thereby can effectively alleviate the corrosion failure of screw propeller copper alloy surface; But there are defectives such as hole inevitably in hot spray coating; Still can cause the corrosion of matrix, cathode protection then can address this problem, and the matrix corrosion under the Coating defect is effectively suppressed.Simultaneously owing to there is insulating ceramic coating to exist; Can significantly alleviate the galvanic corrosion effect between copper alloy screw propeller and the steel hull; Make the required more exposed surface of protection current of copper alloy screw propeller significantly reduce, help optimizing the cathode protection effect of whole hull (containing screw propeller).On the other hand, because the existence of insulating ceramics coating has been arranged, can make the metal nonpolluting coating on surface can not obtain cathode protection, the copper nonpolluting coating can form the surface with antifouling effect in the process of spontaneous corrosion, thereby prevents adhering to of marine life.
The present invention adopts method scale removal such as sandblast earlier and obtains the surface of even roughness to copper alloy screw propeller surface; Adopt heat spraying method coating spray metal adhesive coating then from the teeth outwards; The sprayed on material of bonding coat is the self-adhesive aluminum bronze powder, has good compatibility between it and the copper alloy matrix.The thickness of spraying bonding coat is 30-100 μ m.Suitable bonding coat thickness can improve the anchoring strength between cramic coat and the copper alloy matrix.Prepare the metal oxide ceramic insulating coating in bond coat surface then, the material of metal oxide ceramic insulating coating comprises the one-component oxide, like pure Al

2Polynary composite powder, the cramic coat that adopts the composite powder spraying to obtain is organized more even compact, pore-solids ratio is lower.Adopt the nano-scale oxide powder can obtain more excellent property of coating.This insulating ceramic coating adopts the heat spraying method preparation, like plasma spraying.The cramic coat coating thickness is 100-200 μ m.On the insulating ceramic coating for preparing, adopt heat spraying method to prepare the metal nonpolluting coating, the metal nonpolluting coating is fine copper or the copper alloy with antifouling effect, and its thickness is 50-200 μ m.The metal nonpolluting coating can prevent that not only the stained of marine life from adhering to, and can further strengthen the protection to copper alloy screw propeller matrix.
The present invention applies cathode protection to screw propeller and can adopt sacrificial anode also can adopt the impressed current method.When adopting sacrificial anode, can adopt zinc alloy or aluminum alloy anode material, be arranged on the hull or be directly installed on (sacrificial anode is processed army cap) on the screw propeller.When adopting impressed current cathodic protection, the shaft grounding device that needs to adopt slip ring and carbon brush to form electrically connects screw propeller and hull, makes screw propeller obtain cathodic protection current.
Compared with prior art; Technical method of the present invention can solve propeller erosion and sea marine organism pollution problem simultaneously; Pottery and metallic coating have higher binding force and longer protection life-span than organic coating, and insulating ceramic coating has reduced the current requirement of cathode protection of ship.After adopting this method, the speed of a ship or plane that can prevent to cause owing to screw propeller is stained reduces, and because of corrosion and the stained maintenance and repair work capacity that causes, but cost saving and ensure the performance of marine technology performance.
