Abstract

The invention belongs to the technical field of environment test and observation. An impeller blade provided with teeth at the edge is utilized for rotating and flapping a test medium to produce waves and stirring liquid to move, and by virtue of comprehensive adjustment of liquid level in a corrosion test box, rotating speed of the blade and height of a sample frame, three corrosion regional environments, namely a splash zone, a tidal and splash zone and an immersion zone are simulated at the same time. The accelerated corrosion test device capable of simulating the marine environment is composed of a test box, an impeller provided with a driving system, the sample frame and the test medium, wherein the impeller is horizontally arranged in the test box (1) in the axial direction, an impeller shaft (2) is arranged above the liquid level, a blade (3) is a toothlike edge, and the sample frame (4) is fixed on the inner wall and/or bottom of the test box. The accelerated corrosion test device provided by the invention is simple in structure, strong in designability, wide in application range, easy to operate and high in efficiency, can simulate marine environment corrosion tests in different corrosion areas and different intensities, guarantees repeatability of test results and is applicable to simulation of the marine environment corrosion tests on various marine materials and components.

Description

technical field [0001] The invention belongs to the technical field of environmental testing and observation, and relates to marine environment simulation test technology, in particular to the simulation marine corrosion test technology in splash zone, tidal range zone and full immersion zone. Background technique [0002] The environmental test of corrosion resistance in marine environment is an important means to evaluate the life of materials and improve the reliability of equipment. The corrosion of the marine environment is usually divided into five areas, namely, the sea atmosphere area, the splash area, the tidal range area, the full immersion area and the submarine soil area, among which the splash area and the tidal range area are most severely corroded. [0003] At present, the main test methods include natural test of coastal marine corrosion test station and accelerated test of test chamber. The coastal marine corrosion test adopts real sea sampling and sampling...
