Abstract

The invention discloses an electrochemical measuring device and a measuring method for bottom corrosion of a rust layer of a spoondrift splashing region. The electrochemical measuring device for the bottom corrosion of the rust layer of the spoondrift splashing region comprises a sealed dryer, an electrolytic tank, a working electrode, a reference electrode, an auxiliary electrode and mirror wiping paper. The device and the method can be used for measuring corrosion electrochemical behaviors in the spoondrift splashing region of a metal electrode covered by the rust layer, so that convenient and effective means are provided for a research process of the corrosion electrochemical behaviors under the rust layer of the spoondrift splashing region.

Description

technical field [0001] The invention relates to a method for measuring the electrochemical behavior of corrosion, in particular to a device for measuring the electrochemical behavior of corrosion under the rust layer in a wave splash area and a measuring method thereof. Background technique [0002] The marine environment is a complex corrosive environment. The spray splash zone is a known harsh and corrosive environment where sufficient oxygen, constant weathering and wetting of the spray, frequent wet and dry cycles, and high salt concentrations result in extremely corrosive conditions. It is well known that metallic materials suffer severe corrosion in the splash zone. Once the metal material is exposed to the ocean spray splash area, it often forms a rust layer on the surface very quickly. In the spray splash area, the corrosion of the metal material under the rust layer is the longest and most important working state. To study the corrosion control in the spray splash...
