Preparation of CTS Coatings Containing Calcium and Phosphorus on Titanium Surface by the Cathode Liquid Phase Plasma Technology-中国Betway体育网页登陆

摘要 Chitosan(CTS)coatingscontainedcalcium(Ca)andphosphorus(P)ontitanium(Ti)surfacearepreparedbythecathodeliquidphaseplasmatechnology(CLPT),inacertainconcentrationelectrolytesolutionwithselectiveadditionsofammoniumdihydrogenphosphateandcalciumnitrate.Itisindicatedthattheparametersforastabledischargearevoltageof400V,frequencyof100Hz,dutycycleof30%basedonalargeamountofexperimentdata.Themorphology,structureandcompositionofthecoatedsamplesarestudiedbySEM,FTIR,XRD,XPS.Theresultsdemonstratethatthecompositecoatingsareuniform,andsomesolidparticlesofinorganicsaltcontainingcalciumandphosphorusdispersedonthecoatings.CAtestsshowthatthesamplestreatedbytheliquidplasmabecamelesshydrophilic.ThevariationofhydrophilicityontheCLPTtreatedtitaniumisattributedtothechangeofthefunctiongroupsonthesamplesurface.Meanwhile,apossibleformationmechanismofthecompositecoatingsisdiscussed.
