This invention relates to failure.

the monitoring control, namely, the device operates in the following way.

A device with electrodes 1 and 3 is brought into contact with a controlled pair. In this case, the thermopower meter 6 of the thermoelectrodes and the controlled pair of contacting materials form a closed electrical circuit. With the determination of the physicomechanical properties of coatings and metal compounds by the magnitude of thermoEMF, it can be used in the electronic, aviation, engineering and other industrial sectors.

The aim of the invention is to increase, by the power of the heater, the electrode heating the adhesion control accuracy, as a result, in the measuring circuit of touching metals and alloys. Thermoelectric power arises, which is registered. In the drawing, a diagram is presented by meter 6. By changing the lagged device, the CEDP is judged on the quality of adhesion of a thermoelectric device for 5 touching metals and alloys. control of metals and alloys contains: a heating electrode made of material 2 with which it contacts, a cold electrode 3 made in the form of a hollow cylinder from Q other material 4 of this pair, a heater 5 fixedly mounted
