Fabrication of Aluminum with Porous Surface by Mechanical High-energy Ball MillingLIAN Mian-yan, SHEN Yi-fu, GU Dong-dong Naniing University of Aeronautics and Astronautics, Nanjing 211100, ChinaAbstract:The cast aluminum blocks were put together with the PTFE powder, which were mechanical milled by using a high-energy ball mill, then the remainder PTFE on the surfaces of the specimens was removed. The phases and morphology were measured and characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM） respectively. The results show that porous surface can be achieved on the pure aluminum by high-energy planetary ball mill. Confirming the better process parameters, the effect of the PTEE during the milling process was also discussed. The electrochemical corrosion tests were carried out to know the change of corrosion property.[著者文摘]
