摘要： A measurement system permits environmental, corrosion damage, and mechanical property measurements to assess protection properties of coatings. The system includes one or more multi-sensor panels, each multi-sensor panel having sensors for assessing coating barrier properties, free corrosion, and galvanic corrosion. Each multi-sensor panel is installed on a test rack that contains electronics for sensor excitation and sensor data acquisition throughout a corrosion test. Sensor data is collected, stored, and communicated to a base station. A network of multiple test racks can be supported by a base station to compare the performance of different coatings and material combinations simultaneously. The test racks can be used in accelerated atmospheric corrosion tests, outdoor test sites, or application service environments. Measurements of the capacity of a coating to maintain barrier properties, prevent free corrosion, galvanic corrosion, and environment-assisted cracking can be used to develop, select, and predict service performance of coatings.

摘要： A corrosivity associated with each of multiple locations near, on, or within a structure exposed to an environment that can corrode the structure is determined. Each of multiple sensor nodes is mounted at a corresponding one of the locations and measures environmental sensor information using one or more environmental sensors and corrosion sensor information using one or more corrosion sensors. The environmental sensor information is processed to obtain for the sensing node a first atmospheric corrosivity category value in accordance with a corrosivity classification system, and the corrosion sensor information is processed to obtain a second atmospheric corrosivity category value for the sensing node in accordance with the corrosivity classification system. One or more of the first and second atmospheric corrosivity category values is provided for use in determining a corrosion classification value for each of the locations.

摘要： A sensing device includes a pair of contactless electrodes for placement on a coating on a surface of a structure or within or between one or more coatings on or over the surface of the structure. The electrodes function as sensors when activated to generate a current flow through the electrodes at multiple different frequencies. The sensing device also includes contactless control circuitry co-located with or separate from the electrodes that transmits impedance data generated from the activated electrodes. The impedance data is associated with corrosion condition information of the structure and/or the one or more coatings. A data collection system and display system useable with the sensing device are also described.
