The studies of the phase and elemental composition of the surface layer copper electric contact of KPV-604 contactor subjected to electroexplosion spraying of the composite SnO 2 -Ag-system coating were done by the method of transmission electron microscopy. The scale of the elemental structure of the coating's surface varies within a very wide interval after the electroexplosion spraying - from hundreds of micrometers to tens of hundreds of nanometers. According to the morphological feature two layers may be distinguished in the coating's volume: the coating proper and the thermal effect layer smoothly transferring to the bulk of the sample. The nanocrystalline structure was detected. The main phase of the coating are SnO 2 , Ag 3 Sn, Cu 10 Sn 3 , Cu 3 Sn, Cu 6 Sn 5 , Ag 4 Sn and CuO. The volume of copper adjacent to the coating has a structure indicative of the high level of deformation of the sample's surface layer in the electroexplosion method of the coating's formation.
