采用混料回归设计法,对K_2ZrF_6-KC1-LiC1系助镀剂的最佳组成进行了研究,求得了表面指标与组成之间的回归方程,并根据方程绘出了三元系的等值图. 实验采用了特殊设计的溢铝式镀液锅,有效地避免了铝液面上的浮渣以及铝液中由助镀剂所产生的氧化物对镀铝的影响.
The optimal composition of K_2ZrF_6-KC1-LiC1 fluxing agent was studied by using mixed regression design method. The regression equation between surface index and composition was obtained and the isotherm of the ternary system The experiment uses a specially designed overflow aluminum plating bath, which effectively avoids the dross on the aluminum surface and the influence of the oxide produced by the flux on the aluminum plating.
