Titanium　anodes　with　different　combinations　from　Ru-Ti　and　Ir-Ta　were　prepared　by　thermal　decomposition　at　500C.　The　morphologies　and　phase　structures　of　the　titanium　anode　coating　were　analyzed　by　XRD　and　SEM　techniques.　The　results　show　that　the　phases　of　Ti/Ir-Ta/Ru-Ti　anode　coating　are　IrO2,　rutile-type　solid　solution　(Ti,　Ru)O2　and　(Ru,　Ti)O2.　The　Ti/Ru-Ti/Ir-Ta　anode　coating　contains　anatase　TiO2　besides　phases　hereinbefore.　The　phases　of　Ti/Ru-Ti-Ir-Ta　anode　coating　are　rutile-type　solid　solution　(Ti,　Ru,　Ir)O2　and　(Ir,　Ti,　Ru)O2.　Tantalum　exists　in　the　coatings　with　the　form　of　non-crystalline.　The　crystal　lattice　distortion　decreases　with　the　harmonious　distribution　of　the　different　size　ions.　The　formations　of　coatings　possess　characteristics　of　the　structural　epitaxial　growth.　The　morphology　of　Ti/Ir-Ta/Ru-Ti　anode　is　beehive-liked　structure.　The　morphologies　of　Ti/Ru-Ti/Ir-Ta　and　Ti/Ru-Ti/Ir-Ta　anode　are　dry　cracked-mud　like.
