Study of morphology, chemical composition and corrosion resistance of «TiC–NiTi» hard alloy modified by powerful ion beam
The article presents the results of a study of the effect of ion–beam treatment with a high–power ion beam (HPIB) on the change in topography, morphology, chemical composition and corrosion resistance of the surface layers of a tungsten–free hard alloy of the «TiC–NiTi» system. The samples are...

| description | The article presents the results of a study of the effect
of ion–beam treatment with a high–power ion beam
(HPIB) on the change in topography, morphology,
chemical composition and corrosion resistance of the
surface layers of a tungsten–free hard alloy of the
«TiC–NiTi» system. The samples are characterized
by scanning electron microscopy, energy dispersive
X–ray analysis, scanning probe microscopy, and
metallographic analysis. It is revealed that due to
the impact of HPIB, the surface layer of the sample
undergoes melting with the formation of extended
microcracks. At the same time, a decrease in the oxygen
concentration from 24,6 to 13,7 at. % is recorded in the
surface layer of the sample, and at some points on the
sample it is completely absent. This result indicates
the dissociation of titanium oxide under the influence
of temperatures arising during HPIB irradiation. It
is most likely that it is the thermal dissociation of
titanium oxide and melting of the sample surface that are the main reasons for the increase in the corrosion
resistance of the «TiC–NiTi» system alloy. |
