28Plasma electrolytic oxidation — (PEO), also known as microarc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials, so that discharges[1] occur and the resulting… …
29Electroless nickel plating — Electroless nickel plating, or EN , is an electroplating technique used to deposit a layer of nickel phosphorous alloy on a solid work piece, such as metals or plastic. The alloys with different percentage of phosphorus, ranging from 2 5 (low… …
30galvanizing — Protection of iron or steel against exposure to the atmosphere and consequent rusting by application of a zinc coating. Properly applied, galvanizing may protect from atmospheric corrosion for 15–30 years or more. If the coating is damaged, the… …
