Title: Microstructure and wear of iron-based hardfacings reinforced with in-situ synthesized TiB2 particles
Author: M. KAPTANOGLU, M. EROGLU
Abstract: In this study, four hardfacings, reinforced with in-situ synthesized TiB2 particles, were cladded by tungsten inert gas (TIG) welding, applying flux-cored wires with varying Fe-Ti and Fe-B content. Microstructural examination, macrohardness and microhardness measurements and abrasive wear tests were performed. Morphology of TiB2 changed from a small-sized hexagonal and rectangular to a coarse plate-like one with the increasing common proportion of titanium and boron. Accordingly, hardness and wear resistance increased linearly with the changing titanium and boron content in hardfacings.
Keywords: TiB2, wear, microstructure, hardfacing, flux-cored wire
