Boundary lubrication — Brief description of lubricationLubrication is the process, or technique employed to reduce wear of one or both surfaces in relative motion to one another by interposing a substance called lubricant between the surfaces to carry or to help carry… … Wikipedia
boundary lubrication — A phase in lubrication in which a thin film of oil only a few molecules thick separates two rubbing surfaces. It can occur because of a high bearing load, inadequate viscosity, oil starvation, or loss of oil pressure. Boundary lubrication is not… … Aviation dictionary
Lubrication — is the process, or technique employed to reduce wear of one or both surfaces in close proximity, and moving relative to each another, by interposing a substance called lubricant between the surfaces to carry or to help carry the load (pressure… … Wikipedia
lubrication — See lubricate. * * * Introduction of any of various substances between sliding surfaces to reduce wear and friction. Lubricants may secondarily control corrosion, regulate temperature, electrically insulate, remove contaminants, or damp shock.… … Universalium
Hydrodynamic lubrication — Hydrodynamic (HD) lubrication (or fluid film lubrication) has essential elements:#A lubricant, which must be a viscous fluid. #Hydrodynamic flow behavior of fluid between bearing and journal. #The surfaces between which the fluid films move must… … Wikipedia
Lubricity — is the measure of the reduction in friction of a lubricant. The study of lubrication and mechanism wear is called tribology.Measurement of lubricityLubricity of a material cannot be directly measured, so tests are performed to quantify a… … Wikipedia
Hand scraper — A hand scraper is a single edged tool used to scrape metal from a surface. This may be required where a surface needs to be trued, corrected for fit to a mating part, needs to retain oil (usually on a freshly ground surface), or even to give a… … Wikipedia
Dimensionless quantity — In dimensional analysis, a dimensionless quantity or quantity of dimension one is a quantity without an associated physical dimension. It is thus a pure number, and as such always has a dimension of 1.[1] Dimensionless quantities are widely used… … Wikipedia
