VC–VB particles reinforced Fe-based composite coatings with different molybdenum contents were in-situ fabricated by laser cladding. The microstructure and properties of the coatings were systematically investigated by means of micro hardness tester, XRD, SEM, EDS, ring-block wear testing machine and box-type resistance furnace. The results showed that both hardness and wear resistance of the coatings were greatly improved. When the content of Mo exceeds 3%, anti-oxidation of the coating decreased. Through analysing of the oxidation kinetics curves at different temperatures of the samples, it can be found that the coating with 2.5% Mo has the preferable oxidation resistance at 600°C, and its antioxidant property is five times of the coating without Mo, two times of the substrate.
