| 中文摘要: |
| 目的 评估新型纳米涂层体系在海洋、工业大气模拟环境下的耐蚀性能。方法 采用外观评级法、厚度损失分析法、电化学阻抗分析法、疲劳寿命分析法，对比分析新型纳米涂层体系与TB06-9底漆+TS96-71面漆涂层体系在海洋大气、工业大气模拟环境下不同加速周期的光泽、色差、综合评定等级、厚度损失量、疲劳寿命、阻抗特性。结果 随着加速试验加速周期的增加，两类涂层体系综合等级由0级上升至3级、厚度损失量由0 μm逐渐增加至15 μm、电化学阻抗值下降至10 kΩ.cm2，且外部环境谱较内部环境谱、工业大气模拟环境较海洋模拟环境对两类涂层耐蚀性影响较大，但两类涂层体系在各加速谱下作用下，其疲劳寿命循环次数在49 000~55 000次之间，无明显变化。结论 综合分析两类涂层体系腐蚀损伤特性及腐蚀损伤规律，可见纳米涂层具有较好的耐候性，但相比TB06-9底漆+TS96-71面漆涂层体系，其耐蚀性能较差。 |

| The paper aims to evaluate the corrosion resistance of the new nano-coating system in marine atmospheric simulation environment and industrial atmospheric simulation environment.Appearance rating method, thickness loss analysis, electrochemical impedance analysis, fatigue life analysis were adopted to comparatively analyze gloss, chromatic aberration, comprehensive rating, thickness loss, fatigue life, impedance characteristics of new nano coating system and (TB06-9 paint primer + TS96-71) coating system in marine atmospheric environment and industrial atmospheric simulation environment in different accelerating periods.With the increase of acceleration test cycle, the comprehensive level of two kinds of coating system increased from level 0 to 3; the thickness loss increased gradually from 0 μm to 15 μm; the electrochemical impedance values fell to10 kΩ.cm2; and the external environment spectrum had a greater influence on the corrosion resistance of the two kinds of coating compared with internal environment spectrum, so did the industrial atmosphere simulating ocean environment compared with the marine atmosphere simulation environment. But for the two kinds of coating system under different acceleration spectrum, the fatigue life cycles was between 49 000 to 55 000, and there was no obvious change.Based on the comprehensive analysis on the corrosion damage characteristics and corrosion damage rules of the two coating systems, it can be seen that the nano-coating system has a good weathering resistance, but compared with the coating system (TB06-9 primer + TS96-71 topcoat), its corrosion resistance is poor. |
