碩士 / 朝陽科技大學 / 營建工程系碩士班 / 94 / Electroless Nickel-Plated has been known as one of the chemical electroplates. It’s featured by producing the thin film with remarkable surface hardness, wear resistance, corrosion resistance as well as good adhesion which make it a promising method of surface coating on steel used for construction. However, the studies for this Electroless Nickel-Plated is still very limited and not yet widely explored. Accordingly, to further improve the process as to increase the economic benefits of its applications will be remained a critical subject to get studied.
In this paper, we used Electroless Nickel-Plated steel to replace the conventional steel and embedded in three kinds of reinforced concrete specimens (ie: 100% sea sand; partial sea sand and 100% river sand) and immersed in the pool emulated for the environment of sea shore curing pond for long time. At the same time, we put another set of concrete specimens outdoor inside Tai-Chung Harbor as to test the corrosion resistance under rich chorine environment near by the sea shore. Besides, we also performed the freeze-thaw cycling test in order to test the specimen’s capability of resisting the freeze-thaw conditions.
The steel bond stress test showed the excellent corrosion resistance for Electroless Nickel-Plated steel embedded in concrete specimen. And the other steel bond stress test revealed Electroless Nickel-Plated steel has similar performance with the conventional one which means the electroplating has no significant impact on steel bond stress. By the way, based on the correlation in between surface corrosive area and bond strength, it shows the bond strength will be significantly impacted when the steel’s surface corrosive area up to 20% to 30%.
