| Abstract: | 142-145The influence of X-ray radiation of different wave lengths on the structure and properties of electrodeposited copper
coatings is found. It is determined by the methods of X-ray structure analysis and optical and scanning microscopy that, in
the process of electrodeposition, X-ray radiation changes the primary structure of electrolyte and leads to a decrease in
the grain size of deposits and an increase in the microhardness and degree of dispersion of mosaic blocks. The radiation effect
on the process of electrodeposition is accompanied by an increase in the rate of material deposition on the cathode due to
intensification of the diffusion of electrolyte components to the cathode. |
