| The work aims to explore the typical characteristics of hot and humid marine atmospheric environment in China and evaluate and visualize the severity of hot and humid marine atmospheric environment in Hainan with Q235 steel as the benchmark material. With Hainan Island as a typical humid and hot marine atmosphere area, the natural atmospheric environment test was carried out based on 13 stations distributed throughout the island, and the atmospheric environment data and Q235 steel material performance data of each station were collected. By analyzing the apparent morphology, corrosion weight loss and other properties, the corrosion behavior rules of Q235 steel in Hainan atmospheric environment and the corrosion degree differences in different areas of Hainan were explored. Based on the correlation between atmospheric environmental factors and Q235 steel corrosion behaviors, the corrosion sensitive environmental factors were screened and the mapping model of "corrosion weight loss-sensitive environmental factors" was constructed. Based on the corrosion weight loss data of Q235 steel in various regions of Hainan, the distribution map of corrosion weight loss was calculated and drawn through Griddata interpolation. The corrosion behavior differences of Q235 steel in various regions of Hainan was mastered, and the severity of atmospheric corrosion in Hainan was visually displayed. The sensitive environmental factors affecting the corrosion of Q235 steel in Hainan are the distance from the sea and the period with humidity greater than 80%. The severity of atmospheric corrosion is high in the coastal and eastern areas of Hainan, and low in the central and western areas. |
