【 摘 要 】

The corrosion behavior of Zn electrodeposition on mild steel in varying 0.1 to 0.5 M of HCl with and without inhibitor was studied using weight loss measurement and optical microscope. The (OP) results revealed that the corrosion mechanism layers of the zinc plated mild steel without inhibitor has high content corrosivity related to the appearance of cracks due to the dissolution into the acidic medium. However, the zinc electrodeposition with ZnO as an inhibitor in the test medium shows a stable layer formation. The Zn coatings were found to contain an insoluble corrosion products, which act as a corrosion barrier that prevent corrosion from been attacked by the hydrogen presence.
