In　this　paper,　the　flat　tungsten　coatings　with　uniform　grains　were　prepared　via　electrolytic　tungsten　at　1173　K　in　ternary　molten　salt　system　formed　by　tungstate,　tungsten　oxide　and　different　mass　fractions　of　ZrO2.　Dense　tungsten　coatings　containing　the　second　phase　of　ZrO2　were　obtained　by　constant　direct　current　electrodeposition　in　molten　salt,　and　the　coatings　have　preferential　growth　orientation　along　the　(2　1　1)　crystal　plane.　These　coatings　were　characterized　via　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　energy　dispersive　spectrometry　(EDS)　and　laser　scanning　confocal　microscope　(LSCM).　The　results　show　that　W-ZrO2　coating　obtained　at　Na2WO4-WO3-ZrO2.　In　addition,　the　existence　of　zirconia　in　molten　salt　reduced　the　coating　roughness　from　13.567　mu　m　to　3.017　mu　m,　the　current　efficiency　was　lost　from　84.15%　to　70.76%,　and　the　grains　became　fine　and　uniform.　What＇s　more,　the　mechanical　properties　and　thermal　cycle　performance　of　the　coating　have　been　effectively　improved.　To　further　illustrate　the　electrochemical　process,　the　electrochemical　behavior　of　tungsten　ions　and　zirconium　ions　during　the　electrodeposition　was　investigated　by　cyclic　voltammetry　(CV)　and　square　wave　voltammetry　(SWV).　The　results　indicated　that　the　reduction　reactions　of　tungsten　ions　and　zirconium　ions　are　divided　into　two　steps,　and　the　reaction　processes　are　as　follows:　W(VI)　-＞　W(IV)　-＞　W,　Zr(IV)　-＞　Zr(II)　-＞　Zr.
