The ion implantation influence on the microhardness.

The analysis of experimental data to study the change investigation of the carbide composite materials microhardness with the compositions (40TiC–10TiC (UDP)–50TiNi) % and (50TiC–49,5 TiNi–0.5 B) vol.%. was conducted in the article. It is established in the work that during the surface irradiation of polished samples with Ar+ + Zr+ ions with energy of 20 keV with a dose of ∼1017 ion / cm2, there is a significant change in the microhardness of the hard alloys described earlier compositions. Obviously, as a result the materials implantation produces quenched-in point defects caused by intensive heating and cooling of samples. The distribution of point defects is consistent with the surface change in the microhardness of the samples which were subjected to implantation. [ABSTRACT FROM AUTHOR]
