Two　Al2O3-TiB2　composite　coatings　were　deposited　by　axial　plasma　spray　using　two　types　of　feedstocks.　One　of　the　feedstocks　was　a　conventional　micrometre　sized　Al2O3-30　wt-%　TiB2　composite　powder　from　a　self-propagating　high　temperature　synthesis　(SHS)　process.　The　second　was　fabricated　by　spray　drying　SHSed　Al2O3-30　wt-%　TiB2　composite　powder　doped　with　10　mass-%　nanosized　Al2O3　powder.　The　microstructure　of　the　feedstocks　and　as　sprayed　coatings　were　comparatively　investigated　by　scanning　electron　microscope　and　X-ray　diffraction.　Wear　resistance　of　as　sprayed　coatings　were　assessed　using　block　on　ring　wear　test　at　room　temperature.　Results　showed　that　Al2O3-TiB2　composite　coatings　were　composed　of　alpha-Al2O3,　gamma-Al2O3,　TiB2　and　a　small　amount　of　TiO2.　TiB2　that　mostly　remained　in　the　shape　of　undeformed　particle　were　dispersedly　distributed　in　the　matrix　of　the　composite　coatings.　The　coating　from　spray　dried　powder　exhibited　finer　and　denser　microstructure　and　demonstrated　better　wear　resistance　than　the　coating　from　the　SHSed　powder　under　the　same　sliding　conditions.
