  7. Abstract:
  8. The purpose of this study is to increase the strength of metal and polymer compound combinations in the direction of this increase, the electrolytic plasma oxidation coating is applied and its effect will be checked to increase bond strength. Also, due to the failure in the polymeric side of the bonding, the effect of adding short fibers of carbon to polypropylene will be checked on the strength of the polymer and bond strength. The effect of current density at coating application, the presence or absence of short carbon fiber in the polymeric field and the formation of initial hole on aluminum alloy on bond strength was studied. For further analysis, the optical and electron microscopic images of the transverse cross-sectional and EDS analysis were performed to determine the elements in each section of the interfacing section. Voltage-time curve was drawn during the application of the cover and its different areas and mechanisms governing each region were studied. The results showed that the presence of electrolytic oxidation coating increased the bond strength to 1,822 N in a non-hole state and up to 2228 N in a first-hole state .The reason for increased strength, mechanical locks due to the penetration of molten pulp during the process of welding to the porosity of the surface of the coating. The penetration of molten polymer into porosities at the interface was confirmed by optical and electron microscopic images and EDS analysis. It was also observed that, generally, increasing the density of the applied flow of bond strength increased due to the surface morphology of the coating in relation to the density of different currents
