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。The effects of different current density on the alloying element content were discussed. based on the results, the optimal process condition was confirmed : pb ~ ( 2 + ) 80 - 90 g / l sn ~ ( 2 + ) 7 - 15 g / l ch _ 4so _ 3 ( dissociative ) 130 - 150 g / l composite additive 12 ml / l current density 2 - 6 a / dm ~ 2
