Abstract
A method and apparatus for measuring an anodic capacity of a thermally sprayed coating are described. Eddy current techniques are used to probe the coating and resulting RMS voltages are translated into anodic capacity indications which can be standardized or absolute. Recalibration can be achieved using single point measurement.
