    摘要: A test coupon package suitable for a cathodic protection system includes a native test coupon and first and second active coupons. The active coupons may be biased with respect to the soil or other electrolytic medium in which a pipeline protected by the system resides. The first active coupon may have a surface area that will contact an electrolytic medium that is approximately equal to a surface area of the native test coupon that will contact the electrolytic medium. The surface area of the first active coupon may be substantially greater than a surface area of the second active coupon that will contact the electrolytic medium. The test coupon package may include an electrochemically stable reference electrode positioned between the first active coupon and the native coupon. The test coupon package may be substantially cylindrical and, in at least one embodiment, may include a conical nose connected to a first end of the test coupon package with the second active coupon attached to a narrow end of the conical nose.

    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.
