Microthrowing power of electrolytes for the deposition of nickel-iron alloys. I. Components determining the levelling effect of nickel-iron plating electrolytes

Abstract

The microthrowing power of an electrolyte for plating nickel-iron alloy deposits containing organic additives of the Classes I and II was investigated in an effort to determine the contribution of each component of the system. The levelling versus concentration relationships were evaluated for each additive and the iron ions in the electrolyte both separately and in combination. The results show that the main levelling additives in this system are the brightener Class II as well as the iron component in the presence of saccharin.
