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。"stars: their birth, life, and death" is the result of a lifetime of work in the solar realm, embracing the full solar cycle but evincing none of the alleged deficiencies of composition at solar minimum.
