Coating Delamination Corrosion Monitoring System
System Overview
Based on the coating types and protection statuses of offshore wind power equipment in different zones, electrochemical sensors are researched and designed. A combined measurement approach integrating a coupled array of multiple electrodes with electrochemical impedance spectroscopy (EIS) is employed to enable real-time monitoring of coating aging and damage at various locations, as well as the corrosion status of the underlying steel structures. This allows for an assessment of the protective performance of the coatings and provides guidance for subsequent anti-corrosion scheme design, including coating selection.
System Principles
The coating itself has a porous structure, often containing defects such as pores, cracks, and particle agglomerates. When the coating surface comes into contact with an electrolyte solution, the electrolyte penetrates the coating pores, bringing the metallic substrate into direct contact with the solution; therefore, electrochemical methods can be employed to evaluate the coating’s performance.

Product Features
♦ Enables real-time monitoring of the coating aging process, providing timely data for preventive maintenance to address coating damage;
♦ Electrochemical impedance spectroscopy can provide data such as the interfacial capacitance and phase angle at the coating/metal substrate interface, which can then be used to calculate the coating conductivity and the coating aging rate.
♦ By measuring multi-channel coupled currents, the delamination rate of coated areas and the metal corrosion damage rate can be calculated in real time;
♦ Real-time acquisition of environmental parameters such as temperature and humidity is possible;
♦ Data can be transmitted over a wireless network to the terminal’s central control center and integrated into the user’s comprehensive data management platform, thereby ensuring data security.
