Different　protective　oxide-coatings,　including　SiO　2,　Al　2O　3　and　ZrO　2,　were　prepared　on　the　stainless　steel　(SS304)　by　sol-gel　method.　The　crystalline　phases　and　microstructure　of　these　coatings　were　characterized　using　X-ray　diffraction　(XRD)　and　scanning　electron　microscopy　(SEM),　respectively.　The　high-temperature　oxidation　resistance,　the　thermal　shock　resistance　and　electrochemical　corrosion　resistance　(in　3.5wt%　NaCl　solution)　of　the　samples　coated　with　different　oxides　were　also　compared.　The　results　show　that　the　Al　2O　3　coating　exhibits　the　best　high　temperature　oxidation　resistance　and　electrochemical　corrosion　resistance　and　the　ZrO　2　coating　has　the　best　thermal　shock　resistance　among　these　coatings.
