镍铁合金镀液中光亮剂的整平作用的研究

镍铁合金镀液中光亮剂的整平作用的研究 A STUDY ON THE LEVELLING MECHAMISM OF THE BRIGHTENER IN THE NICKEL-IRON ALLOY ELECTROPLATING 黄清安 first-author 陈永言 左正忠 陆强 胡新振 本文用旋转电极法和假正弦波法测量了光亮剂ABSN的整平能力,结果表明:光亮剂ABSN具有正整平作用,并且整平能力随电流密度的增加而增加。用极谱法和电势扫描法研究了光亮剂ABSN的阴极行为,结果表明:饱和醇及其衍生物（ABSN）能在电极上还原,光亮剂ABSN的整平作用机理符合O·Kardos理论。我们发现:在不同转速的线性扫描伏安曲线上有一个结点并称之为"整平节"。提出了"整平节"的概念,同时作了简要的分析。 The levelling power and cathodic behaviour of a brightener "ABSN" in the bright nickel—iron alloy electroplating were studied with the rotating—disc eletrodic, the false sinewave profilometric, the polarographic and potentiodynamic methods. It has been shown that the brightener "ABSN" has positive levelling power and the revelling power increases with increasing current density of the cathod, and it could be reduced on the cathod. The levelling behaviour of the brightener "ABSN" is in agreement with adsorption—diffuse theory of O’·Kardos. We have found out that there is a node on the curves of liner sweep voltammetry（LSV）and it is named a "Levelling node", and it functions have been explained in brief. 1986-04-01 2021-04-01 4
