Abstract

One of the main approaches to improve osseous integration properties of titanium implants is to obtain micro- and nanoscale roughness of surface. This work compares the influence of various modes of cluster ion processing on topology and wet ability of titanium surface and its interaction with precursor cells of bone tissue. The advantage of this technology of surface processing, based on the action of intensive oriented cluster flows of inert gas atoms, is capability to modify surface topology at nanolevel without chemical additives. Samples after eight processing modes have been analyzed with various impact time, cathode current, solenoid current, rotation speed, and heating parameters. The impact modes have been detected, which lead to decrease in the average roughness of surface and the sizes of surface irregularities, variations of its hydrophilic and hydrophobic properties. Despite the absence of direct correlation of surface roughness and wettability with cell adhesion, the processing modes have been detected providing reliable decrease and increase in surface adhesive properties, which is attractive for development of cluster beam surface modification of titanium implants.
