Abstract: A method of and system for surface finishing an additive manufactured part. A part having a surface roughness with macroasperities is placed in a chamber with an electrolyte and an electrode. A pulse/pulse reverse power supply is connected to the part rendering it anodic and connected to the electrode rendering it cathodic.

Abstract: A system and method of operating an electrochemical mirror for reversibly controlling the propagation of electromagnetic radiation. The mirror preferably includes a first electrode transmissive substrate which is substantially transparent to the electromagnetic radiation, a second electrode, and an electrolyte containing metal ions between the pair of electrodes. A first cathodic potential is applied across the electrodes to cause the metal ions from the electrolyte to electrodeposit a mirror film on the first electrode transmissive substrate. A second anodic potential is applied across the electrodes to oxidize and strip the metallic mirror film from the first electrode transmissive electrode. After a plurality of deposition and stripping cycles, a cleaning cycle is initiated to remove undissolved reflective material on the first electrode preferably by applying a third potential across the first and second electrodes which is increased to a fourth potential and then decreased back to the third potential.
