Oxidation stability
| Oil glossary |
- Ability of a lubricant to resist natural degradation upon contact with oxygen.
- Ability of a lubricant to resist oxidation and deterioration resulting from high temperatures and/or exposure to air.
- Resistance of lubricants to chemical reaction with oxygen; several test methods are used.

Oxidate, английский
Oxidates, английский
Oxidation, английский
- Reaction of a chemical compound with oxygen, as in a paint film in which oil reacts with oxygen to form a hard dry film.
- The action of making oxides by combining with oxygen or removing hydrogen comment: carbon compounds form oxides when metabolised with oxygen in the body, producing carbon dioxide.
- Окисление
- Окисление. потеря в ходе химической реакции электронов (первоначально этот термин означал соединение с кислородом, но теперь он употребляется в более широком значении).
- Chemical weathering process involving the reaction between rocks and
- Process in which a molecule loses one or more electrons to another component of the reaction.
- A form of chemical deterioration to which all petroleum products are subject to, and involves the addition of oxygen atoms resulting in degradation. it is accelerated by higher temperatures above 160°f, with the rate of oxidation doubling by each 20°f increase. with fuels and lubricant oils, oxidation produces sludge, varnish, gum and acid, all of which are undesirable.
- Chemical process in which oxygen combines with another substance; enhanced by elevated temperature and the presence of a catalyst, such as copper, water or foreign matter. oxidation of lubricants eventually produces acids and polymers, resulting in metal corrosion and sludge formation. oxidation inhibitors function by interrupting the oxidation process at the first step, the formation of peroxides that serve as catalysts for the entire process (see inhibitors).
- The reaction of an element to oxygen or an oxygen-containing compound.

Oxidation inhibitor, английский
Substance added in small quantities to a petroleum product to increase its oxidation resistance, thereby lengthening its service or storage life; also called anti-oxidant. an oxidation inhibitor may work in one of these ways: (1) by combining with and modifying peroxides (initial oxidation products) to render them harmless, (2) by decomposing the peroxides, or (3) by rendering an oxidation catalyst inert.

Oxidation reaction, английский
Chemical reaction that removes electrons (often as part of h atoms) from donor molecules, leaving them oxidized
Degradation, английский
- Dégradation
- The progressive failure of a machine or lubricant.
- Disintegration of a paint film by heat, moisture, sunlight, or natural causes.
- Debasement and disgrace. the suspension of a petty officer from his station; and also the depriving an officer or soldier of his arms previous to his being delivered over to the civil power for execution.
- In computer systems, a reduction in level of performance or service. degradation in microcomputer performance is indicated by slow response times or frequent pauses for disk access because memory is insufficient to hold an entire program plus the data the program is using.
- The loss of desirable physical properties by a textile material as a result of some process or physical/chemical phenomenon.
Deterioration, английский

- The fact of becoming worse the nurses were worried by the deterioration in the patient’s reactions.
- Разрушение; окисление; изнашивание; старение

Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.

Pag synthetic fluid, английский
Polyalkaline glycol have excellent oxidative and thermal stability, very high vi, excellent film strength and an extremely low tendency to leave deposits on machine surfaces. the low deposit-forming tendency is really due to two properties – the oil’s ability to dissolve deposits and the fact that the oil burns clean. so when they are exposed to a very hot surface or subjected to micro-dieseling by entrained air, pags are less likely to leave residue that will form deposits. pags may also be the only type of base oil with significantly lower fluid friction, which may allow for energy savings. the other unique property of pags is the ability to absorb a great deal of water and maintain lubricity. there are actually two different types of pags – one demulisifies and the other absorbs water. the most common applications for pags are compressors and critical gearing applications. the negatives of pags are their very high cost and the potential to be somewhat hydrolytically unstable.
