The corrosion behavior of nanocrystalline ( nc ) copper bulks with various grain sizes prepared from igc ( inert gas condemsation ) and vacuum annealing in comparison with conventional microcrystalline ( mc ) copper ( as - rolled and electrolytic ) in acid copper sulphate solution and neutral solution containing chlorides under free corrosion conditions and anodic polarizations has been studied using potentiodynamic polarization, potentiometric analysis, cyclic voltammetry and electrochemical impedance spectroscopy. x - ray diffraction was used to estimate the grain size of the annealed nc copper. field emission gun scanning electron microscopy and x - ray energy - dispersive spectroscopy was used to characterize the surface morphology and analyze the surface composition after the polarization and potentiometric test of both nc and mc copper
本文研究了用igc (惰性氣體蒸發凝聚原位溫壓法)制備並真空退火到不同晶粒尺寸的納米晶銅和微米晶銅(冷軋紫銅、電解銅)在酸性硫酸銅溶液和中性含氯溶液中,在自腐蝕狀態和陽極極化狀態下的腐蝕性能。使用了動電勢極化、電位測定、循環伏安法( cv )和電化學阻抗譜( eis )等方法。 x -射線衍射( xrd )的方法用來估算納米晶銅晶粒尺寸。 -
It was revealed that the hexagonal order was destroyed and the phase transition from hexagonal to amorphous structure with the increment of manganese ion, and with the appropriate neutral hexadecylamine ( hda ) with cetyltrimethylammonium bromide ( ctab ) as mixed template, mn - mcm - 41 was synthesized with well uniformly pore size and hexagonal mesostructure for the additional function of n - metal covalent bond, and the ordered structure was mediated by the influence on the packing parameter
表明隨著mn ~ ( 2 + )引入量的增加,導致介孔長程有序結構的破壞,最終引起由六方相向無定型相的轉變。適量中性表面活性劑十六胺的引入以形成混合模板劑,通過在原有靜電作用基礎上增加n -金屬鍵作用,合成結構較為完整的錳摻雜mcm - 41材料。 -
A novel single phase three - level inverter is proposed, which is named hybrid three level inverter. a leg of neutral - point clamped inverter takes place of one of the two legs of the conventional full - bridge inverter. the great advantage is the harmonics of the output voltage is reduced a lot, so the size of the output filter can be reduced greatly
本文提出一種單相復合式全橋三電平逆變器,它是將傳統全橋逆變器的一個橋臂換為中點箝位三電平橋臂,這樣逆變器可以輸出三電平的電壓波形,其諧波含量被大大減小,因此輸出濾波器的大小可以減小。
