For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
直流電沉積時,基質金屬的沉積連續進行,粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附,重新回到溶液中;採用周期換向脈沖時,反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附,同時,反向脈沖電流對基質金屬的溶解作用,也會促進粒子的脫附,因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加,三種鍍層的晶粒都明顯細化,說明al _ 2o _ 3的存在阻止了晶粒的長大,提高了電沉積過程中晶核的形成速率。Preparation for foil material of new nickel matrix alloy
新型高電阻率鎳基合金箔材研製We think increase of the internal resistance of battery is the main problem to the recycle life deteriorating at high rate, besides the influence of the materials. decomposition occurred on positive and negative electrode at high rate current and the interspaces increased. the restrains of swelling and the increase of an oxygen overvoltage can improve the performance of recycle life
對于電池性能衰減的原因,認為除了所使用的材料是影響電池性能的重要因素之外,在溫度和大電流作用下,電池的正負極材料發生裂解,極片內空隙增大,電池內阻性能惡化是引起電池高倍率循環性能惡化的關鍵;通過抑制正極析氧和膨脹,並降低負極合金材料的粉化過程,將有望緩解電池內阻特性的惡化,從而提高電池高倍率充放電循環性能。Thermomechanical treatment ( solution - cold - drawing - aging ) can increase alloys " strength greatly. the alloy in aging after cold - drawing was influenced by the interaction of precipitation and recrystauization. the precipitates not anly can strengthen the matrix but also can restrain recrystauization
形變熱處理(固溶?冷拉?時效)工藝可大大提高合金時效后的最終強度,時效后形變熱處理對電阻率影響很小。分享友人
