摘要

Al ₂ O ₃ /ZrO ₂ composite coating was prepared on 2A70 aluminum alloy by microarc oxidation (MAO) in a phosphate electrolyte containing K ₂ ZrF ₆ . The effects of K ₂ ZrF ₆ in the electrolyte on the coating thickness, surface morphology, elemental composition and abrasive resistance were investigated. The results indicated that the MAO coating thickness increase due to the addition of K ₂ ZrF ₆ in the electrolyte. In the electrolyte containing 6.0 g/L K ₂ ZrF ₆ , the coating was the most uniform and compact. The MAO coating formed in the electrolyte without K ₂ ZrF ₆ was mainly composed of γ-Al ₂ O ₃ and a little α-Al ₂ O ₃ . Zirconium in the form of t-ZrO ₂ was detected in the MAO coatings formed in the electrolyte containing K ₂ ZrF ₆ , and the Zr content increases with increasing concentration of K ₂ ZrF ₆ . A γ-Al ₂ O ₃ and t-ZrO ₂ nanocomposite coating was formed in the electrolyte containing 6.0 g/L K ₂ ZrF ₆ , and which exhibited the highest abrasive resistance.
