Increasing the Anticorrosive Property of Zinc Plating Process with Modified Zeolite
Abstract
The plating is done to protect the material and to increase the material’s corrosion resistance. This study is aimed to increase the corrosion resistance, to reduce the cost of the alkaline zinc plating process and to make it eco-friendlier by adding modified zeolite. In addition, it is aimed to increase the red rust formation time on iron plates by using modified zeolites. Zeolite modifications were carried out in laboratory conditions and they were prepared by using different chemicals, zeolite sizes, and zeolite amounts. Zinc acetate, magnesium chloride, calcium chloride, molybdic acid, and lanthanum (III) nitrate solutions were used for the modification of natural zeolites. Modified zeolites were added to the alkaline zinc plating bath and were subjected to corrosion tests. Corrosion tests are the most important part of this study. Characterization of the modified zeolite samples was performed by FT-IR and SEM analysis. With the SEM analysis results, high resolution images are provided that clearly show the surface morphology of the modified samples. The functional groups in the structure of the zeolites and the bond states in their structures were determined by FT-IR analysis. According to the results obtained, the most effective and applicable modification method with the best anticorrosive effect was determined. The best anticorrosive effect was observed on the plate that was plated with 7 grams, 10 µm zeolite with molybdic acid in experiment 6.
