| 1 | Effects of electrolytes variation on formation of oxide layers of 6061 Al alloys by plasma electrolytic oxidation显示文摘Plasma electrolytic oxidation(PEO) processes were carried out to produce ceramic layers on 6061 aluminum substrates in four kinds of electrolytes such as silicate and aluminate solution with and without sodium fluorosilicate.The PEO processes were carried out under a hybrid voltage(260 V DC combined with 200 V,60 Hz AC amplitude) at room temperature for 5 min.The composition,microstructure and element distribution analyses of the PEO-treated layers were carried out by XRD and SEM & EDS.The effect of the electrolyte contents on the growth mechanism,element distribution and properties of oxide layers were studied.It is obvious that the layers generated in aluminate solutions show smoother surfaces than those in silicate solutions.Moreover,an addition of fluorine ion can effectively control the layer porosity;therefore,it can enhance the properties of the layers. | Kai WANG Bon-Heun KOO Chan-Gyu LEE Young-Joo KIM Sung-Hun LEE Eungsun BYON | 2009 | 中国有色金属学会会刊:英文版2009，19，4： | 6 |
| 2 | Effects of Hybrid Voltages on Oxide Formation on 6061 Al-alloys During Plasma Electrolytic Oxidation显示文摘Plasma electrolytic oxidation(PEO)is carried out on 6061 Al-alloys in a weak alkaline electrolyte containing NaOH,Na2SiO3 and NaCl.Centered on the correlation of composition and structure,analyses by means of X-ray diffration(XRD),scanning electron microscope(SEM)and energy dispersive spectrometry(EDS)are conducted on the specimens,which have been PEO-treated under hybrid voltages of different direct current(DC)values(140-280 V)with constant alternate current(AC)amplitude(200 V).Attention is paid to the composition,properties and growth mechanism of oxide layers formed with hybrid voltages.Moreover,the main effects of DC value are discussed.Ceramic layers with a double-layer structure which combines hard outer and soft inner layers are found to be consist ofα-Al2O3,γ-Al2O3 and mullite.With the DC values increasing,the growth of the ceramic layers tends to have increasingly obvious three-stage feature. | Kai Wang Bon Heun Koo Chan Gyu Lee Young Joo Kim Sunghun Lee Eungsun Byon | 2009 | Chinese Journal of Aeronautics2009，22，5： | 2 |
