Abstract

The study on phase and elemental composition of the surface layer of copper electrical contact of contactor KPV-604, subjected to the electroexplosive deposition of the composite coating of the CdO-Ag system, was carried out by the method of Transmission electron microscopy (TEM). The scale of the elements of coating surface structure after electroexplosive deposition varies in a very wide range – from hundreds of micrometers to tens and hundreds of nanometers. According to the morphological characteristic two layers can be distinguished in the volume of coating: the coating itself and the heat affected layer smoothly transiting into the main volume of the sample.
