根据国内外对有机涂层的研究情况,介绍了有机涂层及其腐蚀失效机理的研究方法和研究方向;指出应采用系统科学的观点将材料及其使用环境作为一个整体考虑;阐述了电化学阻抗技术在涂层腐蚀研究中的重要地位。通过机理理论的研究,建立涂层寿命模型及预测专家系统是涂层失效研究的最终结果。
By looking though the research activities conducted at home and abroad, various experimental techniques for investigation into corrosion failure mechanism of organic coatings were reviewed. It should be pointed out that materials and their environments should be considered as a whole from the system science point of view. The extraordinarily important role of electrochemical impedance spectroscopy (EIS) was emphasized. It was concluded that an appropriate coating life model and an expert system for life prediction should be set up on the basis of further research of failure mechanism of coatings.
