2. Rust converter - Wikipedia

   en.wikipedia.org/wiki/Rust_converter

   Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

5. Anodizing - Wikipedia

   en.wikipedia.org/wiki/Anodizing

   Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be used for several cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add reflected light wave interference effects.

6. Etching - Wikipedia

   en.wikipedia.org/wiki/Etching

   Etching by goldsmiths and other metal-workers in order to decorate metal items such as guns, armour, cups and plates has been known in Europe since the Middle Ages at least, and may go back to antiquity. The elaborate decoration of armour, in Germany at least, was an art probably imported from Italy around the end of the 15th century—little ...

7. Chromate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Chromate_conversion_coating

   The chromate coating process starts with a redox reaction between the hexavalent chromium and the metal. [2] In the case of aluminum, for example, Cr 6+ + Al 0 → Cr 3+ + Al 3+ The resulting trivalent cations react with hydroxide ions in water to form the corresponding hydroxides, or a solid solution of both hydroxides: Cr 3+ + 3 OH − → Cr ...
