摘要：

Al-based　coating　is　prepared　by　arc　spraying　using　Al-based　cored　wire.　High-temperature　oxidation　resistance　and　corrosion　resistance　of　Al-based　coating　are　compared　with　that　of　Fe-Al　coating　and　45CT　coating.　Also　H2S　corrosion　resistance　of　Al-based　coating　is　compared　with　that　of　Fe-Al　coating　and　A304　stainless　steel.　The　results　shows　that　Al-based　coating　has　excellent　high-temperature　oxidation　resistance　under　650°C.　In　the　case　of　saline　corrosion　and　H2S　corrosion,　only　the　surfaces　of　Al-based　coating　are　eroded　and　the　corrosion　surface　is　very　thin.　The　inside　of　the　coatings　is　not　eroded　at　all.　Thus　Al-based　coating　has　excellent　corrosion　resistance.
