The present invention generally provides a porous oxide film by performing plasma electrolytic oxidation in an electrolyte solution containing zinc, strontium, magnesium, manganese, and silicon ions on the surface of a titanium-based alloy used as a main material of an implant. In more detail, an electrolyte solution consisting of calcium acetate, calcium glycerophosphate, zinc acetate, strontium acetate, magnesium acetate, manganese acetate (II), sodium metasilicate and distilled water is used. Implant is prepared by performing a plasma oxidation process using a titanium alloy in detail, forming a titanium alloy, and then sequentially polished and finely polished, washed with distilled water and then ultrasonically cleaned, and titanium alloy prepared in the preparation step Installed in the anode of the digester, and the cathode Preparation of plasma oxidation process in which an electrolyte solution containing zinc, strontium, magnesium, manganese, and silicon is added after installing platinum or carbon rods； plasma is formed by applying a constant voltage and current density to form an oxide film on the titanium alloy. It relates to an electrolyte composition comprising a process step and a completion step of forming an oxide film on the titanium alloy in the plasma forming step, followed by washing with ethanol and distilled water and drying, and an implant manufacturing method including plasma oxidation fixation using the composition. A bioactive oxide film was coated on the surface of the titanium alloy used as an implant using an electrolyte solution containing zinc, strontium, magnesium, manganese and silicon ions to improve biocompatibility. Oxidation The membrane was formed to increase the stability and the degree of bone adhesion during biocombination of the implant, the titanium alloy implant prepared by the plasma electrolytic oxidation process using the electrolyte solution has a high initial fixing force, and has an effect of reducing the treatment
