Abstract
The paper presents experimental results of the investigation of microstructure of copper surface layer after treatment by runaway preionized diffuse discharge in a stream of atmospheric nitrogen. It is shown that after 100,000 processing pulses on the surface of copper specimens, a disoriented surface layer with a depth of up to 200 nm is formed. Moreover, the results of X-ray phase analysis did not reveal changes in the phase composition of the surface. However, as a result of surface treatment by plasma of a diffuse discharge, the lattice becomes larger and the microstress increases.
