Wear resistance of surface layers with subsequent diamond burnishing applied to 40X steel

Abstract. The subject of this study is weld overlays applied with the OK83.28 electrode on 40X steel, which underwent additional hardening through diamond burnishing with a specially designed diamond-tipped tool. The wear resistance of the welded and hardened layers was investigated under dry friction conditions. The wear characteristics of the samples were determined by measuring weight loss. A metallographic analysis of the structure formed in the welded layers after diamond burnishing was conducted. A residual stress analysis in the hardened zone was performed using X-ray diffraction. The microhardness of the hardened layers was measured using the Vickers method with a 50g load.
