Results of computer simulations describing an interaction between a low-temperature multicomponent plasma and an immersed metal substrate are presented. For this purpose, computer model of volume processes in a DC glow discharge in Ar-O2 mixture and a particle model of plasma-solid interaction were created. The interaction is studied not only in case when a constant value of voltage bias on the immersed substrate is kept, but also when sinusoidal voltage bias is applied. A pressure dependence of the sheath region in electronegative plasma is shown, too.
