2
Lubrication Lubrication is the act of applying lubricants and lubrication substances which are capable of reducing friction between moving mechanical parts
3
Asperities All surfaces, no matter how smooth they may appear to the unaided eye, when sufficiently magnified are rough and uneven. This unevenness is know as asperities. Asperities when rubbed together generate particulate
4
Friction Consumes Power Friction is the resistance to relative motion between two bodies in contact. According to the Department of Energy, 62.4% of energy is lost to friction in the engine resulting in the loss of fuel, horsepower & components \\\ Greatest friction occurs by particles the same size as the oil film thickness
5
Adhesion and Cohesion Adhesion is the property of a lubricant that causes it too stick or adhere to the parts lubricated. Cohesion is the property which holds a lubricant together and resist a breakdown of the lubricant under pressure. Adhesion Cohesion Oil molecules Moving Surface Oil molecules slide over each other
6
Relationship of Friction, Cohesion, Adhesion and Lubrication Friction always consumes power and produces heat Any fluid when placed between two surfaces tends to keep them apart and change sliding friction into fluid friction, thus they are said to be lubricated The extent to which lubrication reduces the friction between two surfaces is governed by two factors: 1) The selection of the fluid which has the best proportion of cohesive & adhesive properties. 2) The amount of pressure between the two surfaces To insure lubrication, the layer of fluid must be kept intact, the greater the pressure the more difficult this becomes
7
Weld Junctions Stress Risers Cutting away Surface Roughness Denting Affect 3 Common Types of Wear as a Result of Friction (1) ABRASIVE WEAR(2) ADHESION(3) SURFACE FATIGUE *High pressure pump *Bearings *Gears *Rings & cylinders *Valves *Seals
8
Tribology Since the late 1960’s the field of Tribology – the study of friction, wear and lubrication in fluid systems - has developed sophisticated tests to gain much knowledge into the effects of friction and ways to reduce friction in order to reduce wear, heat and particle contamination.
9
The Problem Friction and heat cause the destruction of asperities resulting in metal particles interrupting the oil film between two surfaces generating more particles These particles react with moisture, impurities and lubricant additives creating corrosive acids that further pit the surface creating new asperities These acids oxidize the lubricant, accelerate wear and rapidly deteriorate the functions of the lubricant resulting in the 3-common wears in the fluid system Thus far you have seen the effects of friction and the challenge facing lubricants under pressure, heat and particle contamination PARTICLES UNDER 5µ CAUSE THE MOST COMPONENT DAMAGE -Dr. E. Rabinowicz of M.I.T. (American Society Of Lubrication Engineers 1981)
10
5 Functions of the Lubricant 1)Friction Reduction 2)Seal 3)Heat removal 4)Cleanse 5)Absorb Shock
11
Challenge of the Lubricant A good lubricant must reduce particulate wear from the interaction of metal-metal contact Even the best lubricants degrade over time, as a result of friction and chemical in the additive package reacting with particulate, moisture, heat and oxygen resulting in acidic properties These acids react with the metal surface causing micro-pitting (asperities) and the vicious cycle begins anew The very anti-wear additive package designed to protect metal-metal contact, turns acidic and become part of the problem
12
The Downfall of Lubricants The typical downfall of a lubricant occurs as a result of an imperfect, temporary and sacrificial boundary layer between surfaces allowing asperity-asperity contact thus introducing particulate into the lube Heat, moisture, air, and metal particulates combined with certain additives interact causing acids which micro pit the surfaces and oxidizes the oil The efficiency & longevity of a lubricant dramatically increases as the asperity-asperity contact decreases The goal is to reduce friction through a solid and permanent boundary layer on the surfaces
13
Boundary Additives The intent of boundary additives are to form a boundary layer of molecules to prevent surface-surface contact Additives in use are Graphite, Molybdenum, Zinc, Phosphorous, and Sulfur Downside of these additives are their chemical reaction with metal and other contaminates such as moisture causing them to become acidic, corrosive and a part of the problem they are intended to solve These additives are also highly toxic; such as Zinc that is linked to cancer and other illnesses The field of Tribology over the years has researched for a solid boundary lubricant that is biodegradable and permanent.
14
Dept. Of Energy The Present Condition of Friction Loss of horsepower or power in hydraulics Graduated loss of fuel economy Frequent oil drains due to degradation Component wear Increased emissions Rising maintenance cost Rising labor cost
15
18% Decrease in Horsepower Extending oil drains without friction protection this engine dropped from 365 HP to 300HP “Wear promoted by particles (under 10µ) leads to diminished fuel efficiency, reduced component life, oil service, and power output” -Needelman, Filtration For Wear Control & Affects of Contamination

17
The “Big Bang” Discovery In Friction Reduction Technology Following years of research in support of the US space program, a discovery in 1990 by scientist at the prestigious Argonne National Laboratory redefined the potential of lubrication technology Argonne Website: www.anl.gov
18
The Discovery In 1991 the DOE patented boric acid as a solid boundary- layer lubricant. Developed by Dr. Erdemir, Boron CLS Bond was the result of years of research at the Argonne National Laboratories Tribology Department under the Department of Energy Winner of the prestigious R&D 100 award Holds a U.S. DOE Government patent #5,431,830 BORON CLS BOND has been tested worldwide under the harshest conditions with millions spent and producing the same consistent results every time Written up in Journals of Tribology. Lubrication Engineers and many other publications as a self replenishing solid boundary lubricant
