摘　　要：用轧制法制备了内含微弧氧化陶瓷颗粒的6061铝合金复合板,证实了微弧氧化铝合金板轧制复合可行性。用撕裂法测试了复合板的结合强度,对复合板剥离面进行了SEM和EDS分析。结果表明,在热轧温度不低于400℃,同时压下率不低于40%的轧制条件下,铝合金板/微弧氧化铝合金板通过轧制可以实现结合。在轧制时铝合金表面硬化层、微弧氧化铝合金表面陶瓷层破裂,陶瓷颗粒卷入界面结合处,复合板两侧铝合金新鲜金属挤出实现冶金结合。Micro-arc oxidation 6061 aluminium alloy clad plate was prepared by rolling which confirm the rolling composite feasibility of aluminum alloy plate .Bonding strength of the plate was tested by tear method and stripped surface was analyzed by SEM and EDS .The results show that aluminum alloy plate and micro-arc oxidation 6061 aluminium alloy plate can be bonded by rolling at the condition of rolling tempreture above 400 ℃and rolling reduction above 40%.During rolling, hardened layer on the aluminium alloy plate surface and ceramic layer on the micro-arc oxidation aluminium alloy plate surface ruptures , and ceramic particles involving in the interface bonding position , thus let the fresh aluminum alloy of the two plates extrude and the metallurgical bonding is obtained .
