Study on chemical composition and optimum working conditions for trivalent chromium electroplating bath |
| 초록 |
Trivalent chromium plating has been one of the most promising substitutes for hexavalent chromium plating as a surface finishing. In particular, trivalent black chromium is one of the selective surfaces which are commonly used in solar thermal systems, decorative uses, and etc,. The goal of this study was to design an electroplating bath, using trivalent chromium ions instead of its hexavalent ions because of its venenosity, for black chromium coating to produce a good metallurgical and light properties at low cost and reproducibility. For the stable condition and excellent plating characteristics of bath, the effect of the additives was investigated. Trivalent black chromium electroplating baths usually contain three main components such as Cr3+, Co2+ or Fe2+ and a weak complexing agent. Additive materials are also used to improve efficiency of the electroplating baths. In this work, the properties of trivalent black chromium plating in the presence of chrome potassium sulfate were analyzed. In this presentation, main factors affecting the plating performance will be suggested at various plating conditions. |
