Increasing the wear resistance of highly loaded parts such as bodies of rotation by the method of vibration rolling

Abstract

The article analyses the increase of durability of operating surfaces of highly loaded machine parts. The advantages of surfaces with regular microgeometry, obtained by vibration rolling method, compared with usual rough surfaces for improvement of operational properties are shown. Tests of samples and control samples from steel 20 and cast iron samples with control samples from steel processed by grinding and vibration rolling are carried out. The results of research on increasing the wear resistance of the surfaces of details with regular microgeometry are given. Wear mechanisms arising at fretting of vibro-rolled samples in comparison with the process of grinding are established.
