摘要：

汽车铝板常见的两种表面形貌MF表面和EDT表面对汽车铝板的性能尤其是冲压成形性能影响较大。选取力学性能接近的具有MF和EDT两种表面形貌的各2种6016汽车铝板，系统研究了表面形貌对6016汽车铝板表面性能和成形性能的影响规律。试验结果表明：EDT铝板的表面粗糙度是MF铝板的2.5~4倍；EDT铝板比MF铝板有更高的成形极限FLD0；MF和EDT两种铝板的表面摩擦系数、弯曲性能和拉深性能相近。

Mill Finish (MF) and Electron Discharge Texture (EDT) commonly existing in the surface of aluminum body sheet (ABS) have a great influence on the properties of ABS, especially the stamping properties. The effects of surface topography on the surface properties and forming properties of 6016 ABS were systematically studied based on two kinds of ABS with MF and EDT surface topography and similar mechanical properties. The results show that the roughness of ABS with EDT surface is 2.5 to 4 times that of ABS with MF surface, ABS with EDT surface has higher forming limit FLD0 than the one with MF surface, and the friction properties, FLD0, bending and drawing properties of 6016 ABS with MF and EDT surface textures are similar.
