Mixed lubrication is a cross between boundary and hydrodynamic lubrication. In order for full-film conditions to be met, the lubricating film must be thicker than the length of the asperities. In fact, not all that causes friction (e.g., fluid friction) causes wear, and not all that causes wear (e.g., cavitational erosion) causes friction. hbspt.cta.load(3951034, 'c99217f3-09e7-4751-bc3a-7739dac44a0e', {}); Wes Cash is the director of technical services for Noria Corporation. { bidder: 'openx', params: { unit: '539971065', delDomain: 'idm-d.openx.net' }}, At full film elastohydrodynamic lubrication the generated lubricant film completely separates the surfaces. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_rightslot_flex' }}, This page was last edited on 4 September 2020, at 18:45. googletag.pubads().setTargeting("cdo_pc", "dictionary"); "loggedIn": false { bidder: 'sovrn', params: { tagid: '387232' }}, Lubricants can be solids (such as molybdenum disulfide MoS2),[1] solid/liquid dispersions (such as grease), liquids (such as oil or water), liquid-liquid dispersions[citation needed] or gases. ga('set', 'dimension2', "entry"); var mapping_houseslot_a = googletag.sizeMapping().addSize([963, 0], [300, 250]).addSize([0, 0], []).build(); { bidder: 'sovrn', params: { tagid: '346693' }}, { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_leftslot_160x600' }}, window.ga=window.ga||function(){(ga.q=ga.q||[]).push(arguments)};ga.l=+new Date; } Reducing friction is a key objective of lubrication, but there are many other benefits of this process. { bidder: 'onemobile', params: { dcn: '8a9690ab01717182962182bb50ce0007', pos: 'cdo_btmslot_mobile_flex' }}, iasLog("criterion : cdo_dc = english"); 'buckets': [{ { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_rightslot2_flex' }}, { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_btmslot_300x250' }},
