Metal-basedcomposite coatings containing ceramic reinforced particles are widely used, dueto their comprehensive properties, in order to extend the life of different componentssuch as rollers, pistons and turbines. Among reinforcing particles, tungstencarbide is mostly preferred due to its high hardness, high thermal conductivityand good wettability with the matrix. Therefore, in present study, an iron basedcoating, containing 45 wt% of tungsten carbide was produced, using welding wires,and applied on ductile cast iron substrate by GTAW process. The applied coatingwas then studied in terms of it microstructure and mechanical properties. Forthe mechanical properties, hardness, fracture toughness and wear resistance atin room temperature and 400°C were investigated. Results showed for the roomtemperature wear test due to the presence of graphite in the structure of basemetal, which acted as a lubricant, a protective tribolayer was formed on thewear track, which prevented severe wear at lower applied loads, but at the higherapplied loads, the tribolayer was removed from the surface due to the lowadhesion, which caused severe wear of the base metal. For the hardfaced coating,due to its high hardness
