To　improve　the　hardness　and　wear　properties　of　titanium　alloy,　TiB,　TiC　and　B4C　multi-ceramic　phases　reinforced　titanium　matrix　composite　(TMC)　coatings　were　successfully　prepared　by　laser　cladding　using　Ti6Al4V　and　B4C　mixed　powders　as　raw　materials.　The　effects　of　B4C　content　(3,　6,　7　and　9　wt.%)　on　the　phase　composition,　microstructure,　hardness　and　wear　properties　of　the　TMC　coatings　were　systematically　investigated.　The　results　showed　that　the　TMC　coating　was　mainly　composed　of　in-situ　synthesized　TiB　and　TiC　reinforcements,　retained　B4C　and　α-Ti　matrix.　The　sizes　and　quantities　of　the　in-situ　synthesized　TiB　and　TiC　reinforcements　increased　with　increasing　B4C　content,　and　TiB/TiC　intergrowth　structures　composed　of　TiC　dendrites　and　TiB　hollow　prisms　were　observed　in　the　coatings　with　a　B4C　content　exceeding　7　%.　In　addition,　the　calculated　two-dimensional　lattice　matching　at　the　(111)TiB//(101)TiC　interface　was　only　4.97　%,　which　improved　the　interfacial　stability　of　the　TiB/TiC　intergrowth　structure.　The　Rockwell　hardness　and　microhardness　of　the　TMC　coatings　increased　with　increasing　B4C　content,　and　nanoindentation　tests　demonstrated　that　the　nano-hardness　and　elastic　modulus　of　retained　B4C,　TiB/TiC　intergrowth　structures,　primary　TiB,　and　TiBw　or　TiCp　eutectic　regions　were　higher　than　those　of　the　coating　matrix　and　Ti6Al4V　substrate　in　turn.　The　four　TMC　coatings　exhibited　elevated　wear　resistance,　with　abrasive　wear　identified　as　the　dominant　wear　mechanism,　and　the　superior　wear　resistance　of　the　C7　and　C9　TMC　coatings　was　primarily　attributable　to　the　load　transfer　strengthening　effect　of　the　TiB/TiC　intergrowth　structure,　primary　TiB　and　retained　B4C.　©　2024　Elsevier　B.V.
