為解釋微合金化50crv鋼強韌化機理，本文通過對不同淬火溫度，回火溫度，回火時間下的力學性能指標的對比及顯微分析，認為微合金元素的細化晶粒，馬氏體的回火分解，殘余奧氏體的轉變，第二相的沉澱析出共同決定了微合金鋼的強韌化情況，特別是由於微合金元素的存在，其細化晶粒及其碳氮化物的沉澱析出，導致鋼的良好的強韌性，並且如果工藝滿足第二相的沉澱析出強化大於回火馬氏體分解引起的軟化效應，會在硬度曲線中產生明顯的二次硬化現象。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。Grain amount and area statistic show that medium or fine - grained gold are predominent in these two gold field
