Improvement of Surface Quality and Parts Functional Ability by Vibro-Mechanical Consolidation Treatment and Finishing

Abstract:

The area of actual contact of surfaces is essential for longevity and successful operation of mobile and immobile interfaces of machine parts. Wear resistance of friction surfaces, reliability adjustments, heat conduction, conductivity and several other functional characteristics of parts are closely related to actual contact area, and thus they influence the working ability of part surfaces. In this regards, the area of actual contact can be considered as one of the parameters of surface quality. This contact area presents a formed surface of plastic deformation, after the contact of the vibro-percussion treated environment or device, and is the essential process of consolidation of vibratory treatment and finishing. The formed plastic deformation surface is also a kind of micro relief surface, characterized by multitude closed and superimposed on each other traces of contact with the particles working environment cultivated surface. This paper presents the results of vibro-mechanical treatment research, its influence on treated surface quality and working ability of the samples contact surface made by hardened steel ShKh-15, the nickel steel 40HNS2MA and bronze alloy BROF7-0,2.
