Electroplating Steel Sword with Aluminum

Sanded Blade with 100 grid sand paper.

Cleaned Blade with Muriatic Acid.

Dissolved Aluminum into Muriatic Acid.

Applied Aluminum/ Muriatic Acid to blade with 5 volts (Steel blade = 0 volts ; Al/ Muriatic Acid = 5 volts)

Result: Blade partially plated with Aluminum.
