Rusting, английский
Formation of hydrated iron oxides on the surface of a ferrous (in other words, iron based) component. see also corrosion. 512 glossary s s sampling, partial: testing of less than 100 percent of a production lot. sampling, random partial: partial sampling that is fully random. sampling, specified partial: partial sampling in which a particular frequency or a sequence of sample selection is prescribed. an example of specified partial sampling is the testing of every fifth unit.
Corrosion, английский
- Corrosion
- The decay and loss of a metal due to a chemical reaction between the metal and its environment. it is a transformation process in which the metal passes from its elemental form to a combined (or compound) form.
- Коррозия
- The deterioration of metal or of concrete by chemical or electrochemical reaction resulting from exposure to weathering, moisture, chemicals, or other agents in the environment in which it is placed.
- Reaction between metal and oxygen accelerated by the presence of salt, water or intense heat
- The decay and loss of metal caused by a chemical reaction between the metal and another substance, such as contaminants in a lubricant.
- The deterioration of a metal by chemical or electrochemical reaction with its environment or other material.
- Loss or degradation of metal caused by chemical reaction and appearing as pitting and loss of material. galvanic corrosion is caused by electrical contact between dissimilar metals and by entrapped fluids that permit the electronic interchange of ions between adjoining metal surfaces. mechanisms of corrosion include crevice corrosion and stress corrosion in the form of cracking.
- Потеря или деградация металла, вызванная химической реакцией и проявляющаяся в виде питтинга и потери материала. гальваническая коррозия вызвана электрическим контактом между разнородными металлами и захваченными жидкостями, которые обеспечивают электронный обмен ионами между соседними металлическими поверхностями. механизмы коррозии включают щелевую коррозию и коррозию под напряжением в виде растрескивания.
- Loss or degradation of metal because of chemical reaction. corrosion, crevice: corrosion found in tight crevices or pores (pits) and accelerated by galvanic activity from high ion concentrations. corrosion-erosion: simultaneous occurrence of erosion and corrosion. corrosion, fretting: corrosion facilitated by fretting, particularly where a protective surface has been chafed in a corrosive environment. corrosion, poultice: corrosion occurring under a layer of foreign material (for example, under mud in automobile rocker panels).
- Deterioration of a metal by chemical or electrochemical reaction with its environment. removal of material by chemical attack, such as the rusting of automobile components.1 crack, cold: cracks that occur in a casting after solidification, due to excessive stress generally resulting from nonuniform cooling.1 crack, cooling: cracks in bars of alloy or tool steels resulting from uneven cooling after heating or hot rolling. they are usually deep and lie in a longitudinal direction, but are usually not straight.1 crack, grinding: thermal cracks caused by local overheating of the surface being ground.1 crack, hot: cracks that develop before the casting has completely cooled, as contrasted with cold cracks, that develop after solidification.1 also called hot tear. crack, transverse: cracks at right angles to the length of the test object.1 crack, weld: cracks in weld fusion zones or adjacent base metal. usually a result of thermal expansion or contraction stresses related to temperature changes during welding.1
- Deterioration of a metal by chemical or electrochemical reaction with its environment. removal of material by chemical attack, such as the rusting of automobile components. corrosion, crevice: localized corrosion found in regions where part or assembly geometry limits full exposure to the environment.
- Deterioration of a metal by chemical or electrochemical reaction with its environment, or removal of material by chemical attack (for example, rusting of ferrous automobile components). corrosion, crevice: localized corrosion found in regions where part or assembly geometry limits full exposure to the environment.
