摘要
利用雾化沉积加气动扫描工艺制备了铝锡 -钢双金属复合板 ,并对气动扫描的工艺参数、基板的预热温度和轧制温度进行了研究 ,分析观察了沉积态和轧制态的双金属界面的组织结构 .结果表明 ,在雾化压力 0 .8～ 1.0MPa ,沉积距离 30 0mm时 ,采用气动扫描辅助喷嘴 ,并在 2 0 0℃预热基板 ,可得到一最佳效果双金属板坯 ;在 2 2 0～ 2 30℃轧制后可得到界面粘结牢度达到国标要求的。
A composite AlSn steel bimetal plate was fabricated by spray deposition and gas scanning technique. The effect of process parameters such as scanning rate, preheating temperature of the substrate and rolling temperature were studied. The structure of the bonding interface between the spray deposited Al alloy and the steel substrate was analyzed. The experimental results show that the best deposited plate was obtained when the gas atomization pressure is 0.8～1.0 MPa, the spray distance is 300 mm and the preheating temperature of substrate is 200 ℃. After hot rolling at 220～230 ℃ the composite bimetal plates with a high density and superior interface bonding can be obtained.
