ABSTRACT
This study aim to Development of implant surface modification by electrophoretic deposition and dipping
methods of nanocomposite mixture of TiO2 and ZrO2 with different percentage of mixing to increase surface
roughness and microhardness. Grade (II) commercial pure titanium rod was machined into discs shaped. Discs
were divided into 3 groups according to the types of coating used for each percentage: 1st group coated by
nanocomposite mixture of titanium and zirconium using electrophoretic deposition, 2nd group coated by the
same mixture former using dip technique, 3rd group uncoated commercially pure titanium. Each group were
evaluated by using optical microscope, X-ray diffraction analysis, Atomic Force Microscope, Scanning Electron
Microscope, Energy-Dispersive X-ray investigations and Vickers microhardness measurements. By comparing
between the three groups (EPD, dip and uncoated samples), the EPD coated sample technique was higher in
surface roughness and microhardness test. However, Coating of commercially pure titanium with Nano
composite mixture 70% TiO2 and 30% ZrO2 having more surface roughness than coated with nanocomposite
mixture of 50% TiO2 and 50% ZrO2.
