Abstract
In this study, AISI 4140 steel was boronized using solid state thermochemical boriding technique. The process was carried out at 900°C during 45 minutes, producing a monophasic iron boride (Fe2B) layer with a mean thickness of 49,55 μm. The tribological properties of the boronized samples were examined and compared to electroless nickel plated samples using a pin-on-disk wear test. The wear tracks were evaluated by Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Boronized samples reached faster a steady state friction coefficient than the electroless nickel plated samples and the SEM examinations of the wear surface revealed an abrasive wear mechanism on the wear surface of the boronized samples.
