Tungsten　coatings　were　obtained　on　a　tungsten　substrate　by　molten　salt　electrodeposition　(MSE)　at　50　mA/cm(2)　for　60　min　in　a　NaCl-KCl-NaF-WO3　(0.3385:0.3385:0.25:0.0　73mol)　melt　at　800　degrees　C.　The　MSE　tungsten　coatings　have　rough　rectangular　pyramid　surface　and　special　columnar　grains　structure.　Thermal　fatigue　tests　have　shown　that　the　damage　factor　of　MSE　tungsten　coatings　was　smaller　than　that　of　rolled　tungsten　under　the　same　thermal　loads　and　MSE　tungsten　coatings　displayed　better　thermal　fatigue　properties　compared　to　that　of　rolled　tungsten,　which　was　attributed　to　high　purity,　special　columnar　grains　and　rectangular　pyramid　surface　morphology.
