In earlier investigations it found that in lubricated sliding couples is generated electrical potential difference (GPD). The sensitivity of this tribological index and information quantity contained in it far exceeds than previously used (classical) indicators, like coefficient of friction or temperature. Previous investigations do not allow to draw generalizing conclusions, how the force of the tribological parameters affect the GPD signal value. Selected materials of samples and counter-sample were grouped in pairs, forming various combinations I - the same name materials couple, in which the sample and counter-sample were made of the same material; II - the various name materials couple, in change places pairs, in which the two different materials interchangeably in one case are the samples and the second - counter-samples; III - the various name materials couple, in change places pairs, in which the sample from one material was mated with counter-samples from different materials. The testing materials were selected associations represented by a series of metal lying in the Volta electropotential (galvanic) series, both relatively close to each other, as well as a considerable distance and some of the same metal alloys. In presented investigations it was state that there was no clear relationship between the recorded GPD signal effective potential value and the values of the electropotential (galvanic) series. The GPD signal value is individual feature of the each couple and depends on the type of construction materials each pairs of elements forming the each couple. The GPD signal value is lower for the same name materials couple, in which the sample and counter-sample were made of the same material, than for various materials couple. It was found that in the various name materials couple, in which the two different materials interchangeably in one case are the samples and the second - counter-samples, GPD signal value is different.
