  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。
  2.

  4. With plating time going on, the nano - polycrystal gathering grows in two dimensions, and the new nano - polycrystal layer appears simultaneously on the formerly formed nano - polycrystal surface. because the boundary and defect densities in quenched and tempered 45 steel is higher than those in annealed steel, the nano - polycrystal gatherings formed at its surface at the beginning of electro - deposition are more concentrated, and then their size is smaller. the microstructure of the ni - p alloy coating has closed relation with its phosphorus content with the increase of phosphorus content, the microstructure of coating turns from nano - crystalline to the amorphous

    隨著施鍍時間的延長，納米晶聚晶體在橫向二維生長的同時，在納米晶聚晶體的表面上也進行著三維方向的新的一層聚晶體的生長；在調質態45鋼表面，由於其具有比較高的晶界和缺陷密度，因此在沉積初期，納米晶聚晶體的成核密度也較大，從而在二維方向聚晶體的尺度較小，鍍層沉積初期表現為緻密細小的鱗片狀組織。
  5. On the surface of annealed 45 steel, as the pearlite in it contains cementite phase and has high crystal boundary density, the nucleation and growth of deposits prefer to occur at the pearlite at the beginning during depositioa the coating exists in form of nano - polycrystal layers composed by gathering of nano - sized crystals

    在退火態45鋼表面，由於珠光體組織中含有滲碳體相且具有比較高的晶界密度，因而在沉積初期鍍層優先在此處形核和生長；鍍層在基體表面是以納米尺度的晶粒聚集在一起形成的聚晶體形式存在的。
  6. The diamond crystal is coated with ni, which can increase the cohesive strength between bond and diamond, it also prolongs the life of tools

    在金剛石晶體表面鍍上一層鎳金屬層，增加磨料與結合劑之間的結合力，提高工具的壽命。
  7.
