#metallurgy definition
- 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.
- Brass-plating — The act of brass-plating and its result; a technological process of coating the surface of a metallic object (usually made of steel, iron, or cast iron) with a thin, uniform, and adherent layer of brass. This treatment is carried out through electrolytic (electroplating) or thermal methods, aiming to protect the base material against corrosion and to give it a distinct aesthetic appearance similar to gold.
- Shot-peened — Having undergone the process of shot-peening or shot-blasting; a metallic object, structural part, or hard surface treated by continuous bombardment with a stream of metallic pellets. In a technical sense, it describes the final state of a strain-hardened material whose surface micro-imperfections have been eliminated and whose internal compressive stresses have been industrially optimized to resist chronic fatigue and cracking.
- Aluminizing — The act of aluminizing or coating the surface of an object (metal, glass, mirror) with a thin protective layer of aluminum, achieved through spraying, vacuum deposition, or galvanic processes to enhance reflectivity or corrosion resistance.
- To aluminize — To coat the surface of an object (metal, glass, mirror) with a thin protective layer of aluminum, achieved through spraying, vacuum deposition, or galvanic processes to enhance reflectivity or corrosion resistance.
- Aluminizing — The act of aluminizing and its result; a thermochemical treatment or technological process of depositing a thin layer of aluminum onto the surface of steel, cast iron, or glass objects to protect them from corrosion and oxides or to provide high reflective properties.
- Aluminothermy — A metallurgical process based on the reduction of metal oxides using aluminum in the form of fine powder or granules, a highly exothermic reaction that releases a massive amount of heat and temperatures exceeding two thousand degrees, heavily used for welding railway tracks or obtaining pure metals.
- 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.
- Babbitt metal — An antifriction alloy based on tin, lead, copper, and antimony, widely used in industry for casting or lining the bushings of sleeve bearings. This structural material reduces friction and wear on mechanical components in rotational movement, having the property of melting locally in case of overheating to protect the crankshaft from seizing.
