VARIATION IN THE STRESS STATE OF COPPER ALLOYS UNDER THE ACTION OF COLD AIR PLASMA

An investigation has been conducted into the action of nonequilibrium low-temperature plasma of a high-frequency capacitive discharge in air at a pressure of 133.3 MPa upon the structure of brass and beryllium bronze. The absence of changes in the microstructure of alloys under the action of plasma was established using the target metallography method. It has been shown that the main effect of the plasma action is the formation of static distortions of the abovementioned materials at the level ~0.007·10^–10 m.
