Boundary lubricationThis form of lubrication is essentially a breakdown of hydrodynamic action. At high loads or low speeds, the pressure of the oil film cannot prevent metal-to-metal contact. So the opposing surfaces partially ride on an oil film and partially rub together as surface high points come in contact. Lubrication is provided by lubricant decomposition products or surface-active additives which form a thin, soft, solid film on the metal surfaces and prevent metal-junction adhesion. |
Bourdon TubeA U shaped tube used to measure vacuum. |
Box SectionsParts of the vehicle body - chassis and structural members. |
