Abstract
Description
Technical Field

[0002] The coupon method is to put a metal sample of known mass into the corrosion system, take it out, clean it, weigh it after a certain exposure period, and measure the average corrosion rate based on the change in sample mass. The coupon method is the most commonly used method in factory equipment corrosion detection.
[0003] When conducting static corrosion coupon experiments, the conventional method of using bottle caps to press coupons and suspend thin wires has some shortcomings: first, the operation is inconvenient, usually requiring two people to cooperate to complete, which consumes a lot of man-hours; second, when the bottle cap is pressed and the thin wire is tightened, it is easy to pull the thin wire, causing the hanging height of the coupon to be high and low, resulting in differences in the experimental conditions of each group of coupons; third, because the bottle cap is tightened and pressed against the thin wire, it is easy to damage the thin wire, and the thin wire is easy to break during the 14-day experimental period at 70°C, and the coupon sinks to the bottom of the liquid, which has a great impact on the experimental results. Fourth, when the bottle cap is loosened after the experiment, the damaged thin wire is easy to break, causing the coupon to fall into the liquid or on the test bench, which has a certain impact on the observation of corrosion products on the coupon surface and the corrosion morphology.
