RESHETNIKOV The influence of implantation of inert and chemically active ions on the formation of the composition, structure and modification of the physicochemical properties of thin surface layers of stainless steel 03X18N11, titanium alloy VT6, armco-iron with a carbon film sprayed and armco-iron with titanium-aluminum films sprayed has been studied by AFM, RFES, RSA mechanical and electrochemical tests. It is shown that the implantation of argon, oxygen and nitrogen ions leads to an increase in the corrosion resistance of steel 03X18H11 both in a neutral medium and in an environment containing strong corrosion activators – chloride anions. It is established that under the conditions of implantation of N+ ions into the titanium alloy VT6, the formation of the structural-phase state of the surface layers is determined by the chemical activity of nitrogen atoms to titanium atoms. Irradiation with high pulse repetition frequencies, carbon films on the surface of armco-iron, ion implantation leads to the manifestation of a radiation-thermal effect leading to coagulation of fine particles into larger formations, and this is accompanied by an increase in the microhardness of the films. The effect of mixing with argon ions on the formation of surface coating layers of aluminum and titanium films on an armco-iron substrate has been investigated. The parameters of ion-beam mixing allowing the formation of intermetallic compounds (TiAl) in the surface layers of a sprayed titanium-aluminum film on an armco-iron substrate have been determined. Keywords: X-ray photoelectron spectroscopy, atomic force microscopy, surface layers, stainless steel 03X18H11, titanium alloy VT6, armco-iron, titanium-aluminum films, titanium oxides and nitrides.
