The effect of reaction substrates for the TiC carbide synthesis on the composite layer thickness produced in cast iron was examined. It was found that, at a constant weight of the charge amounting to 0.5 kg, changing the weight of the, placed in mould, stoichiometric mixture of titanium carbide (from 0.01 to 0.04 kg) changed the thickness of the composite layer from 1 to 15 mm. Carbides synthesis starts directly in mould induced by the temperature of molten alloy poured into this mould (1700 K). The TiC carbides formed in this reaction are later, i.e. during alloy solidification, acting as a base composite material. The size of TiC carbides obtained in the synthesis is from 1 to 10 μm. They occur in the layers as locally compact and coagulated forms. Microstructure, chemical composition and structure of the obtained materials were tested by scanning electron microscopy (SEM), X-ray microanalysis (EDS), and X-ray diffraction (XRD).
