Comparative studies of implanted and non-implanted specimens are carried ou
t as model experiments at the test stand according to different testing met
hods. Tested specimens were produced of 15 HGM steel and were implanted wit
h a nitrogen dose of 2X10(17) ions/cm(2) with 120 keV. The results of the s
tudy indicate that nitrogen ion implantation of the 15 HGM steel improves t
he friction coefficient and wear intensity.
