Özet

The present study aimed to enhance wear resistance of 304 stainless steel (SS) reinforced AA7075 aluminum matrix bimetal composite by micro-arc oxidation (MAO) process. Monolithic AA7075 alloy and 304 SS reinforced AA7075 matrix composites with and without MAO coating were subjected to ball-on-disc type tribometer with testing loads of 1, 5, 10 and 15 N. Continuous interfacial reaction layer consisted of θ-Fe ₄ Al ₁₃ and η-Fe ₂ Al ₅ phases was obtained at 304 SS/AA7075 interface. These phases contributed to improvement of the wear resistance of bimetal composite by reducing adhesive wear considerably. With the application of MAO treatment, wear-resistant Al ₂ O ₃ (alumina) layer was formed on the surface of composite. MAO coating provided better wear resistance as compared to the original state of the composite, especially at higher loads during wear tests.
