The structure and phase compositions of TiN coating were investigated by diffraction electron microscopy methods. TiN coating was deposited on stainless steel surface by plasma assisted electric arc method. It is shown that coating obtained has a laminated structure. Size of crystallites, extent of disorientation between coating substructure elements and value of internal elastic stresses are to be found depending on substrate bias voltage.

Effect of irradiation with high power nanosecond pulse ion beams on physical and chemical properties of surface layers, fatigue strength and heat resistance of titanium alloys has been investigated. It was found formation of various shaped crater-like microdefects on the surface of these alloys under the action of ion beam pulses with high current density. The main disadvantages of up-to-date ion accelerators preventing their application on an industrial scale, such as a low uniformity of current density distribution throughout the beam cross section as well as insufficient beam parameters stability.

The change in the structure-phase state of Al-Cu-Mg alloy (D16) implanted with 245 MeV krypton ions up to the doses 1013 and 3.1014 cm-2 has been investigated by transmission electron microscopy method. Implantation leads to a partial dissolution of θ'-phase inclusions and the appearance of fine-dispersion S'-phase precipitates. Both processes (θ'-phase dispersion and S'-phase precipitation) are responsible for the hardening of near-surface layers of implanted alloys.

Dependence of wear resistance of hard alloys on their surface oxidation has been investigated by ultraviolet spectrometry methods. Preliminary surface treatment by power ion beam has a significant effect on the form and intensity of oxidation. The correlation between the parameters of zone structure of polyoxide films formed on the surface of hard alloys and wear resistance of cutting instruments manufactured from these alloys was established. A degree of this correlation is determined by the mechanism of fracture (wear) of a tool material.
