Abstract

Hydroxyapatite/Titania coating on titanium strip by brush coating

Author(s): Mahendra Lakdawala and G M Malik

Dual hydroxyapatite and titania coating was developed on titanium strip with single step by simple brush coating method. Sintering was done at 950 °C. The resultant coating was analyzed for Ca/P ratio, coating surface morphology by SEM, X-ray diffraction, Adhesion test. Uniform hydroxyapatite/titania coating was formed on metal surface after sintering. Scanning electron micrographs showed dense and crack free coating. EDAX analysis showed 1.66 Ca/P ratio, X-ray diffraction study gave peaks both for titanium dioxide and hydroxyapatite. Adhesion strength was found to be more than 35 MPa.
