Tungsten　is　considered　promising　candidate　plasma-facing　materials,　but　as　there　is　little　research　on　tungsten　coatings　as　plasma-facing　materials,　more　studies　are　required.　In　this　paper,　tungsten　coatings　with　pyramidal-like　surface　and　columnar　crystals　were　obtained　on　substrates　by　adjusting　the　electrodepositing　parameters.　The　effects　of　the　electrodepositing　parameters　on　the　behavior　and　mechanism　of　tungsten　coatings　were　studied.　In　addition,　tungsten　coatings　and　rolled　tungsten　were　exposed　to　deuterium　(D)　plasma　under　the　same　irradiation　conditions.　The　irradiation　results　showed　that　there　are　two　D-2　desorption　peaks　in　both　the　tungsten　coatings　and　rolled　tungsten.　The　retention　of　D　in　tungsten　coatings　was　lower　than　that　in　rolled　tungsten;　therefore,　it　was　inferred　that　the　deuterium　irradiation　resistance　of　the　tungsten　coating　is　better　than　that　of　the　rolled　tungsten.　This　study　on　the　deuterium　irradiation　of　tungsten　coatings　provides　a　reference　for　the　application　of　100%　tungsten　plasma-facing　materials　in　nuclear　fusion　reactors.
