摘要：This paper investigates properties of single- and double-layer pad coatings deposited on cultivator points. Thecoatings were deposited by manual metal arc welding (MMA) with ESAB OK. 84.58 coated electrodes using aninverter welder, DEDRA DESi201. Tribological properties were determined with a THT 1000 tribometer. A ballon-disc friction pair was used. Experiments were performed in room temperature, with the sliding speed set equalto 0.3 m/s and two loads: 5 and 20 N. In addition, hardness was measured on the surface and in the cross section ofsamples by a Rockwell hardness test method (scale C). Surface roughness was measured before and after friction,and post-friction surface topography was examined under microscope. Impact strength tests of the coatings withsingle- and double layers of pads were performed. The tools and IT algorithms were used to collect and processthe results of experimental research.
