In the article, the regularities of the influence of structural transformations that occur when modifying current-conducting electrodes of elements from piezoelectric ceramics by the low-energy ribbon-shaped electron stream on the performance characteristics (wear resistance and corrosion resistance) of these electrodes. The technological experiment of obtaining modified electrodes on piezoceramic elements is based on a combined process of thermal deposition of a thin silver coating on piezoelectric ceramics in a vacuum. For two groups of samples (formed by the technology proposed by the authors, silver coatings on piezoelectric elements and coatings obtained in an industrial way), the surface state (microrelief, element composition) and the wear rate were studied.
