Facility and Researches Results of the Frictional Characteristics of Metal – Irradiated-Ceramics Pair

Abstract

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. Damageability 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.
