摘　　要：根据304不锈钢材料在西沙地区典型的热带海洋大气腐蚀的特点,在当量计算的基础上,发展了一种模拟西沙室外大气环境的室内加速腐蚀方法,并从腐蚀动力学特征、腐蚀机理、腐蚀产物等几个方面探讨了304不锈钢材料在我国典型热带海洋地区大气暴露实验结果和室内加速腐蚀实验结果的相关性。研究结果表明,紫外/周期浸润复合加速腐蚀实验在一定程度上能较好地模拟304不锈钢材料在西沙海洋大气环境中的腐蚀行为,通过加速腐蚀实验可以对304不锈钢材料在该地区的大气腐蚀行为进行一定程度的预测。According to the typically tropical marine atmospheric corrosion features in Xisha area, a laboratory-accelerated corrosion method was developed on the base of the equivalent calculation. The correlation between atmosphere exposure in the tropical marine and the accelerated corrosion was studied from the dynamic characteristics, mechanism of corrosion, corrosion products. The results showed that, to some extent, the uv/cycle wet-dry synergistic accelerated corrosion test can simulate the corrosion behavior of 304 stainless steel in the tropical marine atmosphere, which can be predicted by the synergistic accelerated corrosion test.
