Abstract

This paper aims to study the peculiarities of a modified layer in the surface of ultrafine-grained (UFG) Ti-6Al-4V alloy after high energy ion nitrogen implantation. The UFG structure in the alloy was produced by equal channel angular pressing. X-ray diffraction analysis and scratch-testing were applied for the investigation. The influence of low-temperature annealing (400°C during 1 hour) on the substructure parameters and phase composition of the surface layer depending on a number of cycles of ion implantation with annealing was shown in the research. The effect of the UFG structure on mechanisms and strengthening degree of the surface after ion implantation is discussed.
