摘要：

TiO2　coatings　were　produced　by　atmospheric　plasma　spraying　system.　H2　flow　rate　was　adjusted　to　investigate　its　effect　on　the　microstructure,　phase　and　electrical　conductivity　of　TiO2　coatings.　The　results　show　that　TiO2　coating　is　mainly　composed　of　rutile,　anatase　and　deoxidization　phases　Magneli　(TinO2n-1,　n=4-10),　and　the　contents　of　them　depend　on　H2　flow　rate.　With　the　increasing　of　H2　flow　rate,　porosity　decreases,　deoxidization　phase　Magneli　and　the　electrical　conductivity　of　coatings　increase.　The　electrical　conductivity　of　TiO2　coatings　also　increases　with　temperature.
