The analysis of a microstructure and microhardness of plasma TiС–FeNiMo coating on a cylindrical titanic substrate have made after frictional processing (FP) simultaneously two tools from a fast-cutting steel at pressure to 15 MPa. Experiments have executed with rotation of the sample, 900 rpm, and moving of tools along a forming cylindrical substrate with a speed of 0.24 mm/s. Rise a coating temperature to 1123°С at the expense of forces of a friction allows to deform a coating up to its fusion. Process of frictional processing characterized values in the linear speed of a coating at its rotation, normal and shifting pressure, friction factor, the work executed on a track and the relation of work to the area of a track. Coatings has sites with not the dense, dense and melted off microstructure and in this connection disorder of values of microhardness of 2.78–9.80 GPa at loading of 200 G and 3.13–16.81 GPa at loading of 20 G. Places of gaugings with cermet structure have average hardness of 8.55 GPa at loading of 200 G and 14.09 GPa at loading of 20 G.
