Sprayed aluminum coatings placed in a chloride solution possess a stable anodic corrosion potential and a low current of self-dissolution with respect to structural steels. Aluminum coatings from melts first act as the anode and then, when the aluminum surface layer is dissolved, as the cathode. As the carbon content in the steel increases, the thickness of the aluminum layer increases as well, and the duration of the protective effect of the coating becomes longer. The apparent fatigue limit of steels with low cyclic strength placed in chloride solutions increases by 4–5.7 times after electric arc spraying with aluminum; as a result of liquid aluminizing, this limit increases by 2.8–3.2 times. |
