Abstract

The invention relates to the wave splashing zone corrosion field, in particular to a device for simulating a hydrogen permeation behavior under a wave splashing zone corrosion condition. The device is composed of a box body, a spraying system, a time control system, a temperature and humidity measurement system and an electrolytic tank device, wherein the spraying system, the electrolytic tank device and the temperature and humidity sensor are arranged in the box body, a minitype water pump is arranged outside the box body and is connected with the spraying system and the time control system, a drainage hole is formed in the bottom of the box body, and the spraying system and the electrolytic tank device are arranged in the box body oppositely. The device is simple in design and convenient to use, and can be used for automatically simulating and measuring the hydrogen permeation behavior under the wave splashing zone corrosion condition indoors.

Description

technical field [0001] The invention relates to the field of corrosion in the spray splash zone, in particular to a device for hydrogen permeation behavior under corrosion conditions in the spray splash zone. Background technique [0002] In the spray splash area, due to the periodic wetting of seawater, the surface of steel materials is in an alternating state of dry and wet, with high salinity, sufficient oxygen supply and wave impact, and the corrosion is particularly serious. The actual sea test not only requires a lot of manpower and material resources, but also has a long period and is not convenient for testing and observation at any time. Therefore, it is necessary to develop a device that can simulate the corrosion environment in the spray splash zone indoors. [0003] Hydrogen infiltration is one of the main reasons for the failure of marine structural materials. Hydrogen in the environment will enter the metal material in various ways during the use or processing ...
