1搅拌摩擦加工制备铝基梯度功能复合材料及表征显示文摘在6082铝板的凹槽中填充SiC颗粒(平均粒径为27.5μm),用一种新型多步搅拌摩擦加工(FSP)法制备Al/SiC梯度功能复合材料(FGM)。为了得到预先设定的梯度结构,使用3种工具进行FSP,每种工具的搅拌针长度不同,SiC颗粒的体积分数也不同。FSP在室温下进行,其工艺参数如下:1~3道次、旋转速度为900r/min、前进速度为20mm/min。利用扫描电子显微镜(SEM)和三维光学显微镜对梯度功能样品的显微组织进行表征,且测试其耐磨性和显微硬度等力学性能。结果表明,随着FSP道次的增加,SiC颗粒分散更加均匀,材料的显微硬度增加。与未加工的6082铝合金相比,经3道次加工后,其显微硬度提高51.54%。添加SiC颗粒后,Al/SiC梯度功能使复合材料的耐磨性提高。Venkatesh BIKKINA Sadasiva Rao TALASILA Kumar ADEPU 2020Transactions of Nonferrous Metals Society of China2020,30,7:2
