摘　　要：　评述了近年发展起来的硅烷化和原位磷化两种金属涂装预处理新技术和有机涂层金属体系腐蚀降解行为的现代研究方法(红外照相法、红外技术)的最新进展。此两种金属表面处理方法能够显著增强有机涂层与金属基体的结合力,有望取代对环境具有危害的传统磷化和铬酸盐转化技术。红外照相技术可更直观地了解涂层下金属的腐蚀发展过程及腐蚀类型;结合SKP和SAM两种技术能够更深入认识涂层金属发生腐蚀过程中腐蚀电位及腐蚀区域的发展变化。Silanization and in　situ phosphatization techniques of the metal surface developed in recent years are presented. The review on investigating methods of degradation behavior of organic coated metals, such as infrared photography and the combination of scanning kelvin probe (SKP) and scanning acoustic microscopy (SAM), is also provided. Both metal surface pretreatments can provide enhanced adhesion between organic coatings and metallic substrates and probably replace the conventional phosphatizing and chromatizing techniques which are dangerous to the health of human being and environments in industrial application. Infrared photography can give insight into the process of degradation and corrosive types of coated metals. Combination of SKP and SAM can be used to detect the changes of corrosion potential and micro-regions in the interface of coated metals.
