  1. 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

    直流電沉時,基質金屬的沉連續進行,粒在電極表不間嵌入鍍層;單脈沖電沉由於脈沖間歇的存在使得具有較大體的粒會脫附,重新回到溶液中;採用周期換向脈沖時,反向脈沖電流使表荷正電的較大的粒更易從電極表脫附,同時,反向脈沖電流對基質金屬的溶解作用,也會促進粒的脫附,此鍍層中復合粒尺寸最小。隨著鍍層中粒復合量的增加,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,提高了電沉過程中晶核的形成速率。
  2. The properties of cn thin films such as their morphology, component, crystal structure and the bonding structure and the relation between those properties and the gas - phase reaction parameters were discussed, showing that the deposition of p - c3n4 thin film is the compete result of various reaction processes in the dynamics balance conditions ; the process of cn films depo sition is diagnosed in situ through the optical emission spectra technique, the effects of experimental parameters on the concentration of the precursors and the gas - phase reactions in the plasma have been obtained ; the main reaction precursors for film deposition identified ; the relation between the characteristics of cn thin films and the reaction process in the plasma is analyzed. the cn thin films deposition under different substrate temperatures in high pressure pe - pld shows that the si atom of the substrate has participated the cn films growth process, based on this the growth mode of cn thin films on the si substrate is proposed. the further experiment of cn thin films deposition on si substrate scratched by diamond as well as covered with fe catalyzer has been attempted, which indicates that changing the dynamics conditions of the surface reaction can alter the growth characteristic of the cn thin films and can enhance obviously the films growth rate
