The　comparative　study　were　carried　out　on　the　microstructure　as　well　as　the　properties　of　the　coating　prepared　by　atmospheric　plasma　spraying　and　shroud　plasma　spraying.　The　results　showed　that,　compared　to　the　conventional　atmospheric　plasma　sprayed　(APS)　coating,　the　shroud　plasma　sprayed　(SPS)　coating　contained　less　unmelted　or　partially　melted　particles　and　oxide　content,　and　porosity　was　lower.　The　SPS　coating　presented　superior　oxidation　resistance　at　1080°C　than　the　APS　one.　The　reason　owed　to　the　mitigation　of　the　involvement　of　the　surrounding　air　that　caused　turbulent　of　the　plasma,　consequently,　the　particles　were　more　fully　melted　and　less　oxide　formed　in　the　coating.　The　finally　deposited　SPS　coating　was　denser　and　contained　more　Al　element,　which　induced　the　formation　of　compact　Al2O3　layer　at　the　early　stage　of　oxidation.　This　compact　Al2O3　layer　would　slow　down　the　thickening　rate　of　thermally　grown　oxide(TGO)　that　provides　better　resistance　to　the　bond　layer,　therefore　the　SPS　coating　presents　higher　resistance　to　high　temperature　oxidation.
