In this study, the WC reinforced Fe-based composite coatings with various CeO2 contents were fabricated on the H13 hot-working die steel by laser cladding. The high-temperature wear resistance of composite coatings was analysed by friction-abrasion testing machine, white light interferometer, and scanning electron microscope (SEM). The microstructure and microhardness were investigated by SEM and Vickers hardness tester. The influence mechanism of CeO2 on microstructure and wear resistance was explained. The results showed that appropriate CeO2 could effectively refine the microstructure of coatings, and affect the crystal morphology. The microhardness of composite coatings was about 4–5 times that of the die steel substrate. Affected by microstructure and microhardness, the Fe-based composite coatings with CeO2 exhibited a higher high-temperature wear resistance than the substrate.
