Facility And Researches Results Of The Frictional Characteristics Of Metal – Irradiated - Ceramics Pair

The technique and facility for studying of frictional characteristics of metal – ceramics pair are presented. Parameters of samples irradiation on the helium ions linear accelerator with 0.12 and 4 MeV energies are resulted. Samples from TiO₂ and Al₂O₃ at 0.12 MeV beam energy are irradiated. Damage ability and occurrence profiles of target atoms along of helium ions range as sputtering ratios are calculated for the irradiated materials. Dependences of the sputtered atoms quantity on samples depth are resulted. Using this data, calculations on change of samples "superficial" density along of ions range are made. Experimental results of a sliding friction factor measurement depending on cycle's quantity, temperature and irradiation dose are presented. On the basis of microscopic researches conclusions on influence of an irradiation on frictional characteristics of a metal – ceramics pair are drawn. (author)
