The most often encountered laborer as a consequence prosthetic titanium (Ti) implant, failure is infection. Implant surfaces that are antibacterial due to nanoscale titanium modifications appear as an appealing peri-implantitis prevention approach. In this study, composite coating preparation) and antimicrobial properties (hydroxyapatite, hydroxyapatite/nanosilver) on titanium substrate by Micro Arc Oxidation(MAO). Preparation the electrolyte in the electrolyte, cell was an aqueous calcium acetate monohydrate solution of 0.1.3 mol/L ((CH3-COO) 2.. Ca.H 2 O) and 0.0.6 mol/l sodium biphosphate dihydrate (NaH 2 PO 4 .2H 2 O) in distilled, water, pH of electrolyte was 2.3 after that, nano silver was added to the electrolyte in different proportions (0.5, 1, 1.5, 2) g/L, and the coating times were also different (30, 45, 60) sec at a constant voltage 200 V. To observe the morphology a AFM test was done and must be known if there are bacteria present or not on Ti substrate and composite coating (HA, HA/nAg) samples by the antibacterial test. In addition, the surface, roughness was measured to study the extent of bacterial adhesion. The result of the tests for coated samples better compared with the uncoated sample. As a result, in the antibacterial test, composite coatings (HA, HA/nAg) were found to be more effective than Ti samples in destroying bacteria that had formed on their surfaces.
