Citation: Changes in the structure and wear resistance of the surface layer of copper under treatment by nitrogen ion beams / V. P. Sergeev [et al.] // AIP Conference Proceedings. — 2014. — Vol. 1623 : International Conference on Physical Mesomechanics of Multilevel Systems 2014, Tomsk, Russia, 3–5 September 2014 : [proceedings]. — [P. 559-562].
Abstract: The structural-phase state of the treated sample surface was investigated by TEM. It was shown by the TEM and VIMS method that the improvement of tribological properties of the copper samples can be associated with an increase of relaxation ability due to a significant increase of the nitrogen concentration in it, which is accompanied by the refinement of fcc-Cu main phase grain structure and the formation of nanopores or gas bubbles in the ion-modified surface layer. A high-dose implantation of nitrogen ions and copper samples increases the wear resistance in 1.5-4.5 times together with a counterbody from the same material in the argon environment. The microhardness of the copper samples also increases.
