ASSESSMENT OF THE TRIBOLOGICAL PROPERTIES OF HARDFACING WELDING ALLOY Fe-Mn-C-B-Si-Ni-Cr IN DRY FRICTION CONDITIONS
Journal Title: Tribologia - Year 2016, Vol 266, Issue 2
Abstract
The paper assesses the tribological properties of hardfacing coatings produced by gas metal arc welding. Flux-cored wires were used as a welding material. The core mixture was based on the Fe-Mn-C-B-Si-Ni-Cr alloy. Seven types of flux-cored wires with different compositions were prepared. The flux-cored wires had a diameter of 2.4 mm. The tribological assessment was performed with an Amsler tribotester under dry friction conditions at different unit pressures: 3, 7, and 10 MPa. The results demonstrate that the coating L-6 has good tribological properties. The overlay weld had a hardness of 49 HRC. Following friction testing, the coatings were also examined with respect to their microhardness and microstructure.<br/><br/>
