liquid lubricants - Opis:
- This paper presents the analysis of the world source letters [1-60] about liquid lubricants for lubrication of the tribological nodes in space engineering for instance: mineral oils, synthetic hydrocarbons, silicones, perfluoropolyethers (PEPEs), ionic liquids, silicic hydrocarbons. Requirements for liquid lubricants in space applications and research methods for their testing are characterized, among others: four-ball vacuum apparatus and pin-on-disk friction tester for tests in vacuum. The development trends of liquid lubricants for space applications are described, too, e.g. direction of development of lubricant substances, development of lubricating substances research and lubrication technologies for space engineering in the future (lubrication systems in inert atmosphere, mist lubrication, lubrication with fine grade powder, deposition of liquid lubricant vapours, gas bearings, magnetic bearings. The existing research methods are imperfect. Till now it is impossible to simulate many factors occurring in space (eg. State of weightlessness, the atmosphere containing the atom oxygen). It is hard to determine precisely (predict) the tribological node wear. There fore the research works on improvement of the existing test stations and analytical, methods and creation of new methods of tests and analysis are necessary.
