Space tribology print that page

Space tribology is a subset of the lubrication field dealing with the reliable performance of satellites and spacecraft (including the space station). It encompasses the entire gamut of tribological regimes, including elastohydrodynamic lubrication (EHL), parched EHL, transient EHL, boundary | 2010/9/25 0:52:16

Friction print that page

performance degradation and/or damage to components. Friction is a component of the science of tribology . Friction is not a fundamental force but occurs because of the electromagnetic forces between charged particles which constitute the surfaces in contact. Because of the complexity of | 2011/10/4 13:13:17

Moving parts print that page


and engineering discipline that deals with the lubrication, friction, and wear of moving parts is tribology , an interdisciplinary field that encompasses materials science , mechanical engineering , chemistry , and mechanics . [ 7 ] [ edit ] Failure As mentioned, wear is a concern for moving

Wear print that page

standardise wear testing for specific applications, which are periodically updated. The Society for Tribology and Lubrication Engineers (STLE) has documented a large number of frictional wear and lubrication tests. But all test methods have inbuilt limitations and do not give a true picture | 2011/5/21 6:25:21

Lubricant print that page

A lubricant is a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles and of distributing heat. The property of reducing friction is known as lubricity . A Good Lubricants possess following characteristics;- 1 | 2011/9/29 6:35:38

Motor oil print that page


Motor oils are derived from petroleum-based and non-petroleum-synthesized chemical compounds. Motor oils today are mainly blended by using base oils composed of hydrocarbons , polyalphaolefins (PAO), and polyinternal olefins [ 2 ] (PIO), thus organic compounds consisting entirely of carbon

Disc brake print that page


The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel while it is in motion. A brake disc (or rotor in American English) is usually made of cast iron , but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites

Contact mechanics print that page


information for the safe and energy efficient design of technical systems and for the study of tribology and indentation hardness . Principles of contacts mechanics can be applied in areas such as locomotive wheel-rail contact, coupling devices, braking systems, tires , bearings , combustion
