Description
Technical Field
The invention belongs to the technical field of material testing.
Background
Cavitation, also known as cavitation, is a major form of damage to flow components of hydraulic machinery such as propellers. The surface of the propeller blade is peeled off in a large area under the action of various factors such as cavitation, corrosion, rust and the like to form a honeycomb surface with bulges and holes, so that the service life of the propeller is greatly shortened, the operation efficiency is reduced, the vibration is intensified, and the safe and reliable operation of the propeller is threatened. In addition, after the ship enters water, marine organisms begin to adhere to the surfaces of parts of the ship, such as a pump, a marine propeller, a turbine blade and the like, and grow, so that the roughness of the surface of the ship is increased, and the working efficiency of power parts, such as the propeller and the like, is reduced. In addition, the propeller is eroded in the sea water, forming electrochemical corrosion, so that the propeller surface is worn. The organic coating is coated on the surface of the flow passage component, so that the surface engineering technology for effectively improving the cavitation erosion resistance, corrosion resistance and antifouling effect of the material is provided, the organic coating has the advantages of low cost, simple construction, convenient coating repair, good cavitation erosion resistance effect, capability of effectively reducing the possibility of electrochemical corrosion of a base material in a cavitation erosion process and the like, and meanwhile, some organic coatings can also reduce bacterial adhesion.
At present, antifouling, anticorrosion and cavitation erosion resistance tests of the organic coating are separately carried out, the cavitation erosion resistance research of the organic coating is only carried out by an ultrasonic cavitation erosion machine, the antifouling performance research of the organic coating is specially carried out by a flat plate coating method and a coating soaking method, and the antifouling performance research of the organic coating is carried out by measurement and research through EIS of an electrochemical workstation.
The surface roughness of the coating becomes larger after cavitation, and the larger roughness provides a larger attachment site for bacteria. The antifouling mechanism of part of organic coatings is that an antifouling release agent is added in the coating, the antifouling release agent is likely to be quickly released under the impact of cavitation bubbles so as to influence the antifouling life, and the pore structure left after the antifouling release agent is released can further influence the anticorrosion capability of the coating, so that the antifouling, anticorrosion and cavitation erosion resistance comprehensively influence the life of the coating, and therefore, a novel multifunctional experiment table integrating antifouling, anticorrosion and cavitation erosion resistance is necessary to be developed, so that the cavitation erosion resistance, the anticorrosion and antifouling performance of the organic coating can be coupled for experiment, and accurate experiment parameters are obtained.
