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。In an aerosol containing equal numbers of charged particles of both signs, the diffusive encounters for oppositely charged particles are more effective than for uncharged particles.
