Analysis of the Characteristics of Nickel-Plating Baths

Abstract


Nickel plating processes, popularly used in Europe in the 1950s, have been increasingly employed in Turkey in recent years. As a result, industrial usage has developed rapidly. Nickel plating is the preferred process for this study because of the uniformity of the plating thickness on the plated surface and the ease with which complex components can be plated. It is also resistant to corrosion and has good levels of hardness.

In this experiment, the following parameters were investigated: the effect of varying the amount of nickel, the thickness of the plating, and sheen (whether shiny or dull).

In this study, brightener and carrier agents have been used to determine the best operational parameters for the Kale Kilit Factory. The compositions of the brightener and carrier agents used in the experiment are included in this text. Additionally, investigations have been conducted on how the plating color changed when compared to the original bath as a result of using Fe2+ complex concentration in nickel plating baths, as a brightener and for analyzing the color of the plated plate, under a visible region spectrophotometer at 350 nm and 6500 Kelvin light power and D65 (Average North Sky Daylight) light. In our research, the most important feature of analysis is that the desired color effect is obtained by using brightener agents containing Fe2+ complex concentration without any interference from any colorant after nickel plating by electrolysis. In a study where nickel plating bath characteristics are researched, physical tests such as brittle test are applied to the plated plates, which provide us important ideas about the accuracy of the choices made according to standards.
