Deoxidizing is different from desmutting in that it removes aluminum oxide off the aluminum substrate via redox (or oxidation-reduction) reactions, something normal mineral acids cannot achieve. You can always desmut aluminum, but you may not always be able to deoxidize aluminum prior to processing.
The red mud waste dries to a very fine, powdery solid and contains significant amounts of iron, aluminum, calcium and sodium. The types and concentrations of minerals present in the muds depend on the composition of the ore and processing conditions.

Filiform corrosion seems to be more prevalent in Europe than in the UK as different powder coating companies will use different types of pre treatment and processing methods compared to the UK. When present, Filiform corrosion reseles “worm-like filaments” that appear under the paint finish and seemingly lift it away from the metal.
The objective of this research was to design aluminum powder metallurgy (PM) alloys and processing strategies that yielded sintered products with thermal properties that rivaled those of the cast and wrought aluminum alloys traditionally employed in heat sink manufacturing. Research has emphasized PM alloys within the Al-Mg-Sn system. In one sub-theme of research, the general processing

Therefore, aluminum alloys are in high demand, and well-suited, for additive manufacturing processing in the automotive and aerospace industries. Even so, there are still some challenges with these alloys if you have a low quality powder, which includes:
Steps in the aluminum extrusion process Billets must be heated to approximately 800-925 F. After a billet reaches the desired temperature, it is transferred to the loader where a thin film of smut or lubricant is added to the billet and to the ram.
