Abstract
The paper reports the consideration of plasma technologies for surface layer strengthening in products, in particular, the strengthening by the impact of low-temperature plasma of the combined discharge allowing the formation of nano-composite structures in a surface layer. By the example of a cutter made of steel R6M5 there are defined basic technological peculiarities of low-temperature plasma strengthening the account of which is possible at the expense of the optimization of parameter values defining the impact of plasma upon a surface. A chart of optimum parameters of a low-temperature plasma strengthening process is obtained. There are presented results of the study of a tool surface layer strengthened with the use of a chart and also tool operation at manufacturing parts made of different materials allowing the establishment of wear resistance increase.
