Zirconium and its alloys have many applications in orthopedic medicine and compared to stainless steel, titanium and other metals used in the manufacture of implants has higher strength and corrosion resistance. Research shows that the method of preparation and surface modification before coating process has a significant impact on improving the metal implants among which include the sandblasting operation. In this glass ceramic is coated on zirconium by sol-gel method and the impact of surface modification procedure on the grip is assessed. First the chemical composition was determined by the quantometric test and then the surface roughness and morphology was analyzed before and after the coating in two sandblasted and non- sandblasted modes was studied by AFM. Coating morphology and structure and creating a structure without separation at the interface was investigated by Scanning Electron Microscope (SEM). Fuzzy analysis was conducted on the samples prepared before and after immersion in SBF solution by X-ray diffraction (XRD) and infrared spectroscopy (FTIR) techniques. The results showed better coating of the surface after the sandblasting and biocompatibility of the coating after placement in the SBF solution.
