Pitting
| Oil glossary |
- A form of extremely localized attack characterized by holes in the metal. pitting is one of the most destructive and insidious forms of corrosion. depending on the environment and the material, a pit may take months, or even years, to become visible.
- Surface irregularities that may develop on lamp pins, bases, and sockets which affect lamp-life and socket operation. tip: replace pitted lamps and sockets asap.
- The formation of hollows in the skin
- Chemical or mechanical surface damage to a metal involving the formation of pits or holes. see also scuffing,
- Forming small sharp cavities in a metal surface by nonuniform electrodeposition or by corrosion.
- Discontinuity consisting of surface cavities. see also cavitation fatigue.
- Forming of small cavity discontinuities in a surface by corrosion, wear, or other degradation. see also cavitation erosion. planck’s distribution law: fundamental law that relates the emitted energy spectral radiance to wavelength and to emitted surface temperature. see also blackbody; incandescence; stefan-boltzmann law; wien’s law.

Cavitation, английский
- Кавитация - явление, возникающее на плавнике на очень большой скорости (срыв потока), за чем неизбежен спин-аут (spin out)
- Formation of an air or vapor pocket (or bubble) due to lowering of pressure in a liquid, often as a result of a solid body, such as a propeller or piston, moving through the liquid; also, the pitting or wearing away of a solid surface as a result of the violent collapse of a vapor bubble. cavitation can occur in a hydraulic system as a result of low fluid levels that draw air into the fluid, producing tiny bubbles that expand followed by rapid implosion, causing metal erosion and eventual pump destruction.
- Кавитация
- Кавитация, образование пустот
- A phenomenon in the flow of water consisting in the formation and the collapse of cavities in water.
- The forming of a cavity
- The formation and collapse of air bubbles created by a ship’s propeller. this reduces effective thrust, creates noise detectible by an enemy, and may cause structural damage.
- The formation of a pocket (bubble) of air or vapor in a liquid, typically resulting from the swift movement of a solid object (such as a propeller or piston) through the liquid. also, the pitting and wearing away of metal or other solid surfaces caused by the collapse of air/vapor pockets in surrounding liquid.
- Describes the continous pumping of mud from surface-level mud tanks, down the drill pipe, out the drill bit nozzles, and through the gap between the drill pipe and the borehole to the surface. this movement carries rock cuttings via the shale shaker to the mud system.
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.

Plain bearing, английский
- A relatively simple and inexpensive bearing typically made of two parts. a rotary plain bearing can be just a shaft running through a hole. a simple linear bearing can be a pair of flat surfaces designed to allow motion.
- Any simple sliding bearing, as distinguished from fixed pad, pivoted pad or rolling bearings. depending on the direction of the load on the bearing surface, plain bearings are classified as guide bearings, journal bearings or thrust bearings.
