pohjametalli
Pohjametalli, in metallurgy, refers to a metal that is not classified as a noble metal. In English, the corresponding term is base metal. Base metals are typically inexpensive, abundant, and more chemically reactive than noble metals such as gold, silver, and platinum. They are prone to corrosion and oxidation unless protected by coatings or alloys.
Base metals often serve as substrates for coatings, as components in alloys, or as the primary metal
Processing and finishing methods are commonly applied to base metals to improve performance. Surface treatments such
Challenges associated with base metals include susceptibility to corrosion, tarnish, and galvanic corrosion when in electrical
