Boride　materials　have　drawn　great　attention　in　surface　engineering　field,　owing　to　their　high　hardness　and　good　wear　resistance.　In　our　previous　work,　a　plasma-sprayed　TiB2-based　cermet　coating　was　deposited,　but　the　coating　toughness　was　significantly　influenced　by　the　formation　of　a　brittle　ternary　phase　(Ni20Ti3B6)　derived　from　the　reaction　between　TiB2　and　metal　binder.　In　order　to　suppress　such　a　reaction　occurred　in　the　high-temperature　spraying　process,　the　high-velocity　oxygen-fuel　spraying　technique　was　applied　to　prepare　the　TiB2-NiCr　coating.　Emphasis　was　paid　on　the　microstructure,　the　mechanical　properties,　and　the　sliding　wearing　performance　of　the　coating.　The　result　showed　that　the　HVOF-sprayed　coating　mainly　consisted　of　hard　ceramic　particles　including　TiB2,　CrB,　and　the　binder　phase.　No　evidence　of　Ni20Ti3B6　phase　was　found　in　the　coating.　The　mechanical　properties　of　HVOF-sprayed　TiB2-NiCr　coating　were　comparable　to　the　conventional　Cr3C2-NiCr　coating.　The　frictional　coefficient　of　the　TiB2-NiCr　coating　was　lower　than　the　Cr3C2-NiCr　coating　when　sliding　against　a　bearing　steel　ball.
