| Abstract Scope |
This research selects a non-ferrous bath extraction process to remove copper from steel based on economic aspects like by-products and experimental conditions(non-vacuum, temperature). To predict the future condition, high copper(4wt.%) synthetic sample is used for the experiments, and SEM-EDS, XRF, ICP-OES, and spark-OES are used to check the composition and diffusion changes. Both aluminum and tin baths react well for surface copper, but the interstitial copper diffusion rate is not viable to adjust in the actual field. In addition, after 20min, aluminum forms an intermetallic compound with steel and growth faster than copper diffusion rate and detaches from the steel. Consequently, this steel debris poison the by-product(Al-Cu precursor). For the tin bath, the operating temperature is lower than aluminum and also did not form an intermetallic compound but is only adjustable for the simple shape samples. |
