摘　　要：采用微弧氧化技术在不同Mn含量的铝合金门窗表面进行了改性处理,研究了基体合金元素Mn对表面陶瓷层膜厚、显微硬度、形貌和物相的影响,并分析了其作用机理。结果表明,随着微弧氧化时间的增加,含0.5%Mn和含1.5%Mn的铝合金试样的表面陶瓷层厚度和显微硬度都表现为逐渐增加的趋势,且在相同的微弧氧化时间内,含1.5%Mn的铝合金试样的表面陶瓷层厚度更大、显微硬度更低。Mn含量为0.5%的铝合金表面陶瓷层中有γ-Al_2O_3相和少量α-Al_2O_3相,而Mn含量为1.5%的铝合金表面陶瓷层中只有γ-Al_2O_3相。The surface of aluminum doors and windows with different Mn content was modified by microarc oxidation technology, and the effect of Mn content on membrane thickness, microhardness, morphology and phase of the ceramic coating was studied, and the mechanism was analyzed. The results show that, with the increase of micro arc oxidation time,the thickness and microhardness of aluminum specimens with 0.5% Mn and 1.5% Mn increase, and in the same time of micro arc oxidation, the ceramic coating on aluminum specimens with 1.5% Mn has greater thickness and smaller microhardness; the phase of ceramic coating on aluminum specimens with 0.5% Mn are γ-Al2O3 phase and a small amount of α-Al2O3 phase, while the phase of ceramic coating on aluminum specimens with 1.5% Mn is only γ-Al2O3 phase.
