The features of the synthesis of a composite coating based on η-carbide (Fe,W)₆C and tungsten applied to an iron substrate have been studied. Coatings are produced by high-speed selective laser sintering of WFe powders mechanically alloyed in a liquid hydrocarbon. The phase composition of the coating starts its formation from the nucleation and growth of (Fe,W)₆C carbide inclusions of up to 400 nm in size. The applied coating has a hardness of 16 GPa, high wear resistance, and friction coefficient of 0.22 to 0.28 measured in dry fretting wear test with steel and WC–Co balls under a load of 10 to 100 N.
