Abstract

This study takes simulated materials of bronze cultural relics (copper-tin al-loy-plated quartz crystal oscillators) as the research object, adopts the Quartz Crystal Microbalance (QCM) technology, and systematically investigates the ef-fects of different temperature and humidity conditions on their corrosion. Three temperature levels (20 °C, 25 °C, and 30 °C) and corresponding gradient levels of relative humidity were set in the experiment. By monitoring the changes in fre-quency and mass of the quartz crystal oscillators, the corrosion kinetic rules were analyzed. The results show that temperature and humidity exert a significant in-fluence on the corrosion of the simulated materials: under constant temperature, the higher the relative humidity, the thicker the water film on the metal surface, the greater the dissolved amount of pollutants, and the faster the corrosion rate; under constant humidity, an increase in temperature will accelerate the corrosion reac-tion, and the higher the relative humidity, the more pronounced the accelerating effect of temperature. Based on the experimental data, a classification standard for temperature and humidity levels was formulated. It is recommended that the long-term storage environment of bronze cultural relics in museums should be controlled at a temperature of (20–25) °C and a relative humidity below 60 %. The conclusions of this study provide a scientific basis for museums in tourist scenar-ios to precisely regulate temperature and humidity, optimize passenger flow management, and improve protection measures, thereby facilitating the achieve-ment of a win-win situation for the coordinated and sustainable development of bronze cultural relic protection and the tourism industry.
