국문 초록 (Abstract)

Sargent 浴內에서 陰極試料의 回轉이 偏心, 硬度 및 析出量에 미치는 效果를 檢討하여 다음과 같은 結果를 얻었다.
(l) 陰極試料의 回轉에 依해서 偏心은 鍍金된 두께의 5%以下까지 減少되었다.
(2) 回轉線速度가 20×10^(-4) m/ses인 경우에는 析出量과 表面組織의 均一性이 增加되었다.
(3) 回轉線速度가 20×10^(-4) m/sec 以上인 경우에는 析出量이 減少되고 陰極表面에 밀림무늬가 나타났다.

The effect of Rotation of cathode on eccentricity, hardness and deposited quantities were investigated by rotating of cathode sample in the Sargent bath. And following results are obtained ;
(1) The eccentricities were decreased below 5% of the deposited thickness by rotating of cathode.
(2) The deposited quantities and uniformity of surface structure were increased at the linear velocity of 20×10^(-4) m/sec.
(3) The deposited quantities were decreased when the linear velocity is elevated more than 20×10^(-4) m/sec and the pushed pattern was appeared on the cathode surface.
