Özet:

The surfaces of metal materials working in industrial environments and harsh environmental conditions deteriorate over time depending on the factors in the environment. Metal materials whose surface deteriorates lose both their corrosion resistance and mechanical properties. One of the preferred methods for improving surface properties is metal coating application. Metal coatings are applied both to improve mechanical properties and to prevent material loss due to corrosion. Electroless plating, which is one of the metal plating methods, is a chemical reduction process based on the catalytic reduction of the metallic ion from the aqueous solution with a reducing agent without electric current and its deposition on the surface of the metal. Many metals such as gold, nickel, copper, silver can be coated with electroless plating method. Electroless nickel plating is the most commonly preferred type of plating in the industry due to its chemical, physical and mechanical properties. In addition, this method makes the production of multi-alloy and composite coatings popular in metal coating works. In this study, electroless nickel plating process was applied to the aluminum material surface and the effects of the working parameters determined for the coating process on the coating thickness, adhesion strength and corrosion resistance were investigated.
