Analysis of the Characteristics of Nickel-Plating Baths

Abstract

Nickel plating processes, popularly used in Europe since 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, brightening and carrying agents have been used to determine the best operational parameters for the Kale Kilit Factory. The compositions of the brightening and carrying agents used in the experiment are included in this text. Additionally, investigations were conducted on how the plating color changed when compared to the original bath as a result of using Fe 2+ complex concentration in nickel plating baths, as a brightening agent and for analyzing the color of the plated sample, 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 brightening agents containing Fe 2+ complex concentration without any interference from any colorant after nickel plating by electrolysis. In this study where nickel plating bath characteristics are researched, physical tests such as brittle test are applied to the plated materials, which provide us important ideas about the accuracy of the choices made according to standards.

Effects of novel additives for zinc-nickel alloy plating

“…This is a situation that negatively affects the quality of the coating. Salt complexes such as tetraethylene pentamine are used to prevent the precipitation of Ni ions [35,36]. Table 5.…”

Electrochemical Deposition of Ni, NiCo Alloy and NiCo–Ceramic Composite Coatings—A Critical Review

“…The Ni chloride acts an additional source of Ni 2+ ions in the electrolyte and this influences the thickness of the deposited coatings. The Cl − ions from the Ni chloride increases conductivity of the electrolyte solution by causing dissolution of Ni anodes [72,73]. Internal stresses in deposited coatings have been observed to decrease where chlorides are absent in electrolytes.…”
