| 中文摘要: |
| 用电化学的方法研究了高频脉冲电镀Ni-Co复合镀层在NaCI溶液中的耐蚀性，结果表明：随着频率的增加，沉积速率提高，沉积层表面更加致密、均匀，在3.5% NaCl溶液中Ni-Co镀层的腐蚀失重明显减小，腐蚀失重速率变慢；高频和直流电铸Ni-Co复合镀层的阳极极化曲线形状相似，随频率增加，自腐蚀电位正移，自腐蚀电流降低。可见，高频率对沉积层的细化有重要影响，并使镀层的耐蚀性提高。 |
| 英文摘要: |
| The corrosion resistance of high frequency pulse electroforming Ni-Co coating in 3. 50-/o NaCl solution was studied. The results indicated that, as the frequency increased, the depositing rate got improved, the coating tended to be more compact and the weight loss rate of the film immersed in 3. 50-/o NaCl solution decreased. The anodic polarization curves for the platings electroformed at high frequency were similar to that for the platings electroformed at DC. As the frequency increased, Ecorr shifted in positive direction, /con decreased. Thus high frequency was of great impact on the deposited layers and improved the corrosion resistance of the plating. |
