RADIATION MODIFIED ION-IMPLANTED BALLS OF BALL BEARINGS

Abstract

A radiation-modified ion-implanted ball of 1/4 inch diameter ball bearings made of 440C steel was investigated. The tuning modification was carried out by ion beam-assisted/enhanced deposition (IBAD / IBED) methods. The surface of the samples was coated with a nanosize multilayer coating of VN-TiN- ... VN (11 layers with a thickness of 100 nm each layer, an energy of 30 keV and a fluence of ~1017 ions / cm2. Hardness of the Modified Ion-Implanted Balls of Ball Bearings is more than the hardness of the original steel by 1.8 times. The results of the study show that IBAD / IBED methods can be used as an effective tool for improving the parameters of ball bearings.
