Corrosion erosion
| Глоссарий по тестированию |
- Accelerated loss of material because of the simultaneous actions of erosion and corrosion when exposed to a moving corrosive liquid. corrosion, exfoliation: corrosion that progresses parallel to the outer surface of the metal along grain boundaries oriented in the rolling direction causing layers of the metal to be elevated by the formation of corrosion product. usually associated with aluminum products.

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.

Corrosion embrittlement, английский
- The severe loss of ductility of a metal, resulting from corrosive attack, usually intergranular and often not visually apparent.
- Severe loss of ductility of a metal, resulting from corrosive attack, usually intergranular and often not visually apparent.
Corrosion fatigue, английский
- Effect of the application of repeated or fluctuating stresses in a corrosive environment characterized by shorter life than would be encountered as a result of either the repeated or fluctuating stresses alone or the corrosive environment alone.
- Fatigue cracking caused by repeated load applications on metal in a corrosive environment. corrosion, fretting: wear caused by repeated small relative movements between mating surfaces. transferred material and freshly exposed surfaces quickly corrode, often forming a product harder than the parent material, thus increasing the wear rate. see also false brinelling. corrosion, poultice: corrosion occurring under a layer of foreign material (for example, under mud in automobile rocker panels).

Corrosion inhibitor, английский
- Additive for protecting lubricated metal surfaces against chemical attack by water or other contaminants. there are several types of corrosion inhibitors. polar compounds wet the metal surface preferentially, protecting it with a film of oil. other compounds may absorb water by incorporating it in a water-in-oil emulsion so that only the oil touches the metal surface. another type of corrosion inhibitor combines chemically with the metal to present a non-reactive surface.
- An additive that protects lubricated metal surfaces against chemical attack by water or other contaminants.
- Additive that protects metal surfaces from chemical attack by water or other contaminants.

Exfoliation, английский
- Peeling, swelling, or scaling of stone or mineral surfaces in thin layers; caused by chemical or physical weathering or by heat. minerals such as vermiculite expand to many times their original size when heat-treated. exh on drawings, abbr. for “exhaust.”
- The loss of layers of tissue such as sunburnt skin
- Отслаивание; шелушение
- The process by which concentric scales, plates, or shells of rock, from less than a centimeter to several meters in thickness, are successively spalled or stripped from the bare surface of a large rock mass. it often results in a rounded rock mass or dome-shaped hill. gg
- Process by which thin, curvilinear scales or shells or rock are
- Exfoliation is the process of removing dead skin cells from your skin. it can be both physical or manual (using a scrub or tool to slough off dead skin cells) and chemical (with acids or enzymes that dissolve dead skin cells).
- A type of corrosion that progresses approximately parallel to the outer surface of the metal, causing layers of the metal to be elevated by the formation of corrosion product.
- Corrosion that progresses approximately parallel to the outer surface of the metal, causing layers of the metal to be elevated by the formation of corrosion product.

Boundaries, английский
The boundaries that determine the direct and indirect emissions associated with operations owned or controlled by the reporting company. this assessment allows a fund manager to establish which operations and sources cause direct and indirect emissions, and to decide which indirect emissions to include which are a result of its operations. see also the following definitions on financial control, operational control and equity share.
Associated, английский
- Соответствующий; связанный; присоединенный
- Experiencing through your own senses (seeing through your own eyes, hearing with your own ears, feeling with your own feelings.)
