Abstract
Operational characteristics of parts in many respects depend on properties of surfaces formed in
the course of machining. To improve the properties of a part surface various methods of machining
are used. One of prospective ways of improving surface properties of parts is the application of
antifriction coatings together with surface and plastic deformation of the surface layer. The
implementation of such a combined scheme of part machining by turning and rolling makes it
possible to apply an antifriction coating on a part, to remove oxide films and other pollution of the
surface and to increase machining performance. As a result of the work done a mathematical model
describing the process of coating formation on a juvenile surface in combined machining by turning
and rolling which can be used for both high-quality research of this process and quantitative
calculation of the formed surface layer parameters was developed.
