Cu electrodeposition was performed on a cylindrical AZ80 substrate with a U-shaped surface. A uniform deposition of Cu was achieved on an AZ80 electrode via galvanostatic etching, followed by Cu electrodeposition in an eco-friendly alkaline Cu plating bath. Improper wetting and lower rotational speeds of the AZ80 electrode resulted in an uneven Cu deposition at the inner upper site of the U-sha...

Chromium-rich electroplating sludge (CRES) is a hazardous solid waste with high content of moisture requiring efficient drying before subsequent treatment. In this study, the microwave kinetics CRES were examined. The results showed that had good absorptivity, contributing to much shorter time and better performance compared conventional drying. comparison at 105 °C, 600 W for total removal was...

Electroplating uses aluminum material, where it’s easy to obtain, lighter, and cheaper than other metals. The research goal was determine the ability of electric current power (Al) coated with silver (Ag) by electroplating method, effect magnitude length time coating process took on weight Al Ag strength metal after tested using Brinnell test. method used is compare pure at different currents p...
