Electrochemical impedance spectroscopy of anticorrosive coating/metal system Abstract: In order to explore the anticorrosive organic coating/metal system, the chemical composition and scale corrosion products of electrochemical impedance spectroscopy in 3.5 wt% NaCl solution were analyzed by laser Raman microscope and mode. The organic coating/metal system was observed by scanning electron microscope (SEM). The characteristics and delamination process of organic coating/metal system are systematically studied, with emphasis on the coating/metal interface in the middle and transition period of corrosion transmission. The results show that the impedance of C 1 coating with corrosion product film decreases at the initial immersion, increases at the dielectric immersion, and finally decreases. Th é destroyed the scale of corrosion products. With the extension of soaking time,

Organic coating is a common method. Metal organic coating can corrode metals. Water, oxygen and corrosive ions are three important factors to prevent corrosive ions from passing through. Share. In order to evaluate the durability of the coating, it is very important to unravel the corrosive inner coating and the coating/metal system on the interface by ion transport. General methods are used to evaluate salt spray, wet heat aging and ultraviolet aging of coatings. These methods can only determine the nature of coating surface corrosion. However, the change of corrosion rate cannot be audited.

Electrochemical impedance spectroscopy (information system) is an internal coating and coating/metal interface system commonly used to study corrosion process. Information system is a powerful tool, which can provide value. Such double .. 1 layer capacitance and polarization resistance. By changing these parameters into time functions or other variables, important information about the dynamic corrosion process can be obtained.

The purpose of this work is to study the corrosion resistance, micro-Raman spectrum measurement and scanning electron microscope (SEM) of organometallic coatings. Evaluate the change of coating/metal interface in corrosive ion coating.
