Abstract
[Introduction]Traditional testing methods,such as artificial salt spray tests and actual environmental exposure tests,for evaluating the corrosion resistance of zinc-coated steel are often time-consuming. The development of equipment and method capable of rapidly testing the corrosion resistance of zinc-coated steel is significant for enhancing the testing efficiency.[Method]A device for continuous on-line rapid testing of the corrosion resistance of zinc-coated steel was designed,which consists of a liquid addition apparatus,a corrosion reactor,and a testing system. The testing process mainly includes corrosion reaction,automatic injection,continuous sampling,and absorbance analysis.[Result]By using the given device,the corrosion resistance testing of zinc-coated steel could be completed within a few hours,significantly reducing the testing time. In addition,the test results were essentially consistent with those of neutral salt spray test.[Conclusion]The given device is easy to operate for quick assessment of the corrosion resistance of zinc-coated steel,indicating broad prospects for application.
