Abstract: The present disclosure discloses a process for evaluating a corrosion inhibitor based on a high-throughput corrosion chip. In the present disclosure, a high-throughput corrosion chip is first prepared by using a chip spotter, and only a corrosion inhibitor and a corrosive substance need to be spotted on a metal sample to quickly, efficiently, and accurately evaluate performance of a corrosion inhibitor formulation, to meet corrosion test conditions such as different substances, different concentrations, and different corrosion duration; and then a corrosion degree of each measurement point in the high-throughput corrosion chip is identified and quantified by using a laser scanning confocal microscope. The high-throughput corrosion chip prepared by using the foregoing method can bear 10-1000 measurement points, and these measurement points can reflect corrosion effects of different inhibitor formulations in different corrosion duration.
