The opportunities for high power ablative pulsed plasma thrusters (APPT) developed at INF, RRC “Kurchatov Institute” within the framework of a program for studying the plasma thrusters — to be used for technological purposses are considered in the paper. An experimentally based description of the plasma flow prodcsed in high power APPT and its interaction with solid surfaces is presented. Experimental data include measured plasma flow parameters and metallographic study of different steels in pulsed plasma flow. It is shown significant increase in steel CT-45 hardness. For the stainless steel the plasma processing resulted in extremely strong reduction in size of grains in the material. An implantation have been obtained with the depth equal 4m and with the concentration — 2—4 %. Experiments have shown the higt power APPT is a competitive tool for surface processing of different materials.
