A　low　friction　coefficient　and　high　bearing　capacity　can　improve　the　service　life　of　implants　in　the　human　body.　In　this　study,　we　firstly　investigate　the　mechanical　properties　of　inorganic　thermal　oxide　coatings　on　titanium　alloy　(Ti6Al4V).　Tribological　experiments　were　performed　for　different　tribo-pairs　under　uniform　conditions.　The　inorganic　thermal　oxide　coating　on　Ti6Al4V　formed　at　300celcius　was　found　to　have　excellent　tribological　properties　and　can　effectively　improve　the　bearing　capacity　of　Ti6Al4V.　The　organic　poly　(vinylphosphonic　acid)　(PVPA)　on　Ti6Al4V　has　excellent　anti-friction　properties,　which　can　help　achieve　superlubricity.　An　inorganic　thermal　oxide/organic　PVPA　composite　coating　was　fabricated　on　Ti6Al4V　to　obtain　a　surface　with　low　friction　and　high　bearing　capacity.　It　is　found　that　the　presence　of　the　thermal　oxide　doubled　the　bearing　capacity　of　the　composite　coating　compared　to　that　of　the　PVPA　coating　alone.　This　study　can　serve　as　a　guide　for　the　modification　of　artificial　joints.
