To　increase　the　strength　and　wear　resistance　of　material　surfaces,　various　combinations　of　B4C　and　80TiFe　powder　were　mixed　into　a　Fe60　self-fluxing　alloy　powder;　the　composite　coatings　reinforced　by　TiB2-TiC　were　successfully　prepared　on　Q235　steel　surfaces　by　laser　cladding.　Scanning　electron　microscopy　(SEM),　energy　dispersive　spectroscopy　(EDS),　and　X-ray　diffraction　(XRD)　were　used　to　study　the　microstructure　and　chemical　and　phase　composition.　Microhardness　and　wear　testers　were　used　to　investigate　the　mechanical　properties.　The　results　show　that　the　interfaces　of　composite　coatings　and　substrate　materials　are　excellent　for　metallurgical　bonding.　The　block-like　TiB2　particles　and　flower-like　TiC　particles　are　uniformly　distributed　in　the　cladding　coating.　When　the　mass　fraction　of　the　mixed　powder　is　30%,　the　average　microhardness　of　the　coating　is　approximately　1100　HV0.2,　which　is　50%　higher　than　that　without　the　mixed　powder,　and　demonstrates　the　best　wear　with　a　performance　twice　as　better　as　that　of　the　substrate.　©　2021　World　Scientific　Publishing　Company.
