Abstract:

   In this study, the wear behavior of boronized AISI 316 stainless steel was investigated. The chemical analysis of the sample to be used in the experiment was carried out with optical emission spectrometry before starting the boronizing experiment. Boronizing experiment using pack-boronizing method were carried out at 950°C for 3 hours. As the boron source, a powder mixture having the commercial name Ekabor 2 consisting of SiC, B4C and KBF4, was used. As a result of the boronizing treatment, the boride layer formed on the surface of AISI 316, morphologically by Scanning Electron Microscope (SEM-BEI), thickness by optical microscope integrated visual analyze system, hardness by Vickers indenter and chemical analysis by XRD (X-ray diffraction) device, were investigated. Then, friction tests were carried out to determine the wear resistance of the boride layer. As a result, it is determined that the boron layer formed on the surface of boronized AISI 316 stainless steel, consists of a double phase iron-boride layer.  This layer is a columnar morphology and homogeneous thickness. Also it has been determined to have ultra-hard and high wear resistance.
