【Abstract】 The mechanism and the affecting factors of erosion-corrosion were discussion. An experiment equipment of accelerating erosion-corrosion in the seawater for metal materials was designed based on the rotation method. The optimizing design of the equipment was accomplished refer to the normal equipment by rotation method. The function of accelerating erosion-corrosion in seawater was achieved by use of the many measurements,such as: torus structure,reverse rushing each other to samples,adding the hard and sharp particle in the flow liquid,and heating the seawater etc. The optimizing designs were accomplished such as: the structure optimizing,motive power calculation,optimizing designs of the key components and parts,heat engineering calculation etc.. The sample machine was made after adjusting and improving for the machine. And the experiment of accelerating erosion-corrosion for Ti samples in seawater was accomplished. The function of accelerating erosion-corrosion was achieved by use of the equipment. It was proved by the result of experiment that the equipment owned some good features,such as: simple and reliable structure,low making cost and low working cost,easy to control and operation,more simulating the actual condition etc. this is a success design because of the reasonable design and good feature,and meeting the design requirements.更多还原
