Abstract

The interaction between vacuum and acidic media significantly impacts the performance of materials, posing a risk of critical component failure in aerospace, chemical, and other fields. To address the issues of long testing cycles and low efficiency in traditional methods, this study develops accelerated testing methods for material acid resistance in a vacuum environment. An experimental system integrating vacuum simulation and dynamic control of acidic media is constructed, using in-situ spectroscopy and microscopic imaging to monitor the corrosion process in real time. By designing accelerated test conditions through multi-parameter coupling, a performance evaluation system based on the thermodynamics and kinetics of corrosion is established. This method reduces the testing cycle by 70%, allowing for precise quantification of material acid resistance, and provides a reliable basis for material screening, process optimization, and equipment safety.
