Abstract
The sliding wear tests were carried out under the condition of constant surface pressure without lubricant at room temperature, using the stationary test pieces of S45C borided steel and the rotary test pieces of low carbon steel. Those tests were carried out with constant sliding distance under various sliding velocity. The scanning electron microscopy and X-ray microanalysis were employed to investigate the wear surface trace of borided steel. The experimental results indicated that the morphology of the wear surface trace largely depended upon the wear mechanism such as oxidative wear, mechanical wear or melting wear. It was concluded that the wear mechanism or the wear life of borided steel could be estimated to some extent with the observation of wear surface trace.
