The current study aimed to manufacture and characterization of three-component nanocomposites Hydroxyapatite Using Polarization Method.. The new work in this paper is an antibacterial test for triple coating which reduces the number of bacteria perceptibly. the antibacterial and corrosion behaviors were evaluated in comparison to uncoated samples by the electrochemical coating polarization test method. Tests such as X-ray diffraction and scanning electron microscope were used to characterize the coating. The X-ray diffraction test results showed that a three-component composite coating was created on the substrate in optimal coating conditions. The scanning electron microscope images revealed that the morphology of the formed coating surface was uniform, and its thickness was about 22 to 26.5 micrometers. The results suggested that coating thickness increased with the progression of coating time. Corrosion test outcomes indicated that employing the nanocomposite layer enhanced the corrosion resistance of the coating. Antibacterial test results suggested that the application of the nanocomposite coating effectively reduced the bacteria growth on the surface.
