| Résumé : |
Tribology may not be a word in your dictionnary or encyclopaedia. It was not in two of mine nor included in an electronic encyclopedia, but was soon found on the internet! It is the science of lubrication and wear and generally studied as part of engineering. For machinery and any moving parts, lubrification is essential to minimise friction and wear and to maximise the use of the energy put into the system.
It has been found that if the two surfaces in contact with each other move slowly then the viscosity of the lubricant should be high; if the surfaces move rapidly then the lubricant should be thin. Oils are the best known form of lubricant but unmodified, have the tendency to thicken as they cool and become thin when hot. They are therefore inefficient at one or other end of the temperature range of the engine. The introduction of viscostatic oils has mainly overcome this problem but there remained the problem of drainage when the thin oil left the contact surface as the engine switched off. It took some time after a restart to get the lubricant to the critical surfaces, whilst meanwhile the surface that rubbed were subject to wear. |
