摘要：

The authors examine the relationships of the parameters of an attached eddy current parametric transducer with the presence and the degree of damage of pipes in the heated surface of thermal power stations made of austenitic steel by intercrystalline corrosion on the side of the external (gas) surface. It is shown that it is principally possible to evaluate the thickness of the damaged layer by the eddy current method. The technical characteristics of the developed VAK-2 specialized device and experience with application of the device under the conditions of thermal electric power stations are described.
