Surface treatment psalter corrosion test equipment at sea

摘要

There is no device to study surface treatment technology because it compares and observes various corrosive factors such as ocean current, salt, and marine adherent creature to improve surface treatment (coating technology such as coating and plating) used in offshore plant and ship. Therefore, the present invention has been made to solve the above problems in view of the stability and reliability of the measured values.This device increases the corrosion resistance and durability by assembling the surface materials of the required materials. The experiment device designed as octagon forms buoyancy with 8 buoyancy boxes, so even if 1 or 2 breaks due to strong winds, the experiment device is not broken, Since the car maintains a constant level of water level, it is possible to keep the intertidal zone and excursion test constant. The specimen stand can be easily inserted and removed from the safety footrest at the top.The space inside the octagon was secured and the electrode bands were placed in the center, and the specimens were equidistantly mounted in eight directions in a radial direction, and the sense was placed to measure the microcurrent generated when the surface treatment specimen was corroded in the sea. By comparing and observing the microcurrents, it was devised to identify the causes of corrosion by simultaneously measuring the effects of various corrosive factors such as currents, salinity, and marine adherence on corrosion.The surface treatment specimen marine corrosion test apparatus according to the present inventionThe effect of various corrosion factors on surface corrosion of marine surface treatment specimens is studied at the same time to improve the international competitiveness of marine and offshore plant industries by developing surface treatment technology for marine structures and offshore plants .
