Influence of plasma of the glow discharge in the environment of argon on the transformation of the structure of an electroplated coating on a copper substrate is investigated. It has been established that the enlargement of the microstructure and the change in the surface morphology are the main results of the effect of transformation of the structure of the electroplated coating of copper. The effect is accompanied by the formation of a new grain at the coating – substrate interface. The microstructure of the copper substrate does not change. According to the results of the texture analysis, it can be assumed that relaxation processes responsible for the change in the structure are recovery (substrate) and polygonization, by which coherence scattering blocks (electroplating) enlargement occurs. It is shown that the enhancement of the deformation texture of the copper substrate is accompanied by a decrease in the level of macrostresses. There are no changes in the microstresses in the galvanic layer and in the substrate.
Keywords: electrodeposited coating, plasma of the glow discharge, surface morphology, texture.
