#industrial coating

• Brass-plated — Having been covered with a protective or decorative layer of brass through technical processes such as electroplating, electrolytic deposition, or thermal immersion; brass-plated. The term applies to various metallic parts made of iron, steel, or zinc to provide them with enhanced corrosion resistance and a refined aesthetic appearance similar to gold.
• Surface passivation — The act of passivating or chemically treating metal surfaces and its result; a technological process of thermochemical or electrochemical surface treatment of a metal or alloy to form a highly resistant protective layer. This structural phenomenon blocks material degradation through corrosion, frictional wear, or high-temperature oxidation, significantly extending the service life of parts in aggressive industrial environments.
• Anti-galling — Designed structurally or chemically treated to prevent, reduce, or eliminate the risk of deep scratching, abrasive wear, or galling of metallic or polymeric surfaces in direct contact and continuous motion. In an industrial sense, it describes a protective layer, a special lubricant, or a guiding device optimized to block mechanical seizing.
• Silver-plate — To coat the surface of an object made of a common metal (such as copper, brass, or steel) or glass with a thin, protective layer of metallic silver, using galvanic, chemical, or thermal evaporation methods; by extension and figuratively, to impart bright white, pearlescent, or lunar reflections to a natural element, such as hair strands or cloudy waters.
