TiC particles that can be wetted by iron-based alloys at elevated temperatures act as the hard phase. The TiC/Fe composite coatings featuring alternating hard and soft phases are cladded on the surface of Q235 steel plates to enhance their service life under wear resistant conditions. The results show that the TiC/Fe composite coatings prepared by laser cladding form a composite structure with alternating hard TiC phase and soft γ-Fe phase. However，when the area ratio of the soft phase to the hard phase is large （greater than 1.8），the “high hardness-antifriction” TiC/Fe composite coatings are not obtained. When the area ratio of the soft γ-Fe phase to the hard TiC phase is approximately 1∶1，a “high hardness-antifriction” synergistic effect is achieved，that is，the average hardness of the alloy coatings is as high as 1300.39HV0.2，and the average coefficient of friction is only 0.1127. The wear mechanism of the iron-based alloy coatings without TiC particles is mixed a wear mechanism of abrasive wear，adhesive wear and oxidative wear. After adding TiC particles，the wear mechanism of the alloy coatings are mainly slight oxidative wear，and with the increase of TiC particles addition，the oxidative wear of the alloy coatings weakens.
