Abstract

The invention provides an in-situ electrochemical test device for simulating acid rain corrosion. The device comprises a liquid storage tank (1), an environment simulating box (4), a control cabinet (12), an electrochemical working cabinet (8) and a computer which are connected in series, wherein a multi-jet nozzle (3) of the liquid storage tank (1) extends to a position above a bracket (7) in the environment simulating box (4), an input end of the electrochemical working cabinet (8) extends to a position above the bracket (7) in the environment simulating box (4), an output end of the electrochemical working cabinet (8) is connected with the computer. When the in-situ electrochemical test device for simulating acid rain corrosion is in use, at least two samples to be tested are used as electrodes (6) and are respectively connected with the input ends of the electrochemical working cabinet (8), and thus the in-situ electrochemical test can be fulfilled. The in-situ electrochemical test device has the following advantages: (1) the instantaneous corrosion rate of acid rain can be obtained; (2) various acid rain corrosion processes can be simulated; (3) a corrosion test in an acid rain environment can be implemented; and (4) the device is simple in structure, low in cost, convenient to operate and easy to maintain.

Description

technical field [0001] The invention belongs to the technical field of metal corrosion, and relates to an in-situ electrochemical test device for simulating acid rain corrosion. Background technique [0002] Since the 1970s, acid rain has gradually become a worldwide public hazard. In Southwest China, Central China, and South China, more than one-third of the country's land area is seriously polluted by acid rain, and the pH value of rainfall is less than 4.5. Because the corrosion of outdoor metal facilities and devices caused by acid rain has caused great losses to the national economy, it is of great practical significance to study acid rain corrosion. At present, the methods for studying acid rain corrosion mainly include outdoor hanging method, rainwater immersion method, dry-wet cycle method, SO 2 (Sulfur dioxide) corrosion test chamber method, among which the outdoor hanging piece method is the most common method to study the acid rain corrosion rate, and is the bes...
