How Do You Become A Tribologist?

1 Tribology. Tribology is defined as ‘the study of friction, wear and lubrication, and design of bearings, science of interacting surfaces in relative motion‘ (Concise Oxford Dictionary, ‘tribo-‘ is derived from the Greek word ‘tribos’, meaning rubbing and friction).

What is the study of lubricants called?

Tribology is the study of the science and technology of interacting surfaces in relative motion and encompasses the study and application of friction, wear, lubrication and related design aspects. To further understand tribology, it is important to understand the definitions behind friction, wear and lubrication.

What is a Tribo pair?

Back to tribology, a tribo-pair is the physical realization of a kinematic pair and the tribo- pairs in total in a machine system constitutes the main part of a tribo-system.

What is seizure wear?

Galling seizure occurs when, during sliding, the surface roughening and the formation of wear particles eliminates the clearance within a sliding component and brings on press-fit conditions. This type of seizure is catastrophic and irreversible.

What is the difference between zero wear and measurable wear?

Zero wear means, there is a wear, but that is not going to cause as much. In fact, it may increase the performance it is for betterment, so that is not undesirable; however, measurable wear where the undesirable wear occurs or undesirable removal of material occurs, just you highlight that.

What is it called when the rubbing surfaces are separated from each other by a very thin film of lubricant?

Explanation: When the rubbing surfaces are separated from each other by a very thin film of lubricant it is known as boundary lubrication. When the two solid surfaces sliding over each other are free from contaminating fluid or film, the resistance encountered is called dry friction.

What does a Tribologist do?

Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication, and wear. … People who work in the field of tribology are referred to as tribologists.

How does a Tribometer work?

During a typical test, a ball is slid on an angle along a track until it impacts a surface and then bounces off of the surface. The friction produced in the contact between the ball and the surface results in a horizontal force on the surface and a rotational force on the ball.

What is a Tribolayer?

Noun. tribolayer (plural tribolayers) A tribological layer of lubricant between moving surfaces.

What is the name of lubrication?

Many different substances can be used to lubricate a surface. Oil and grease are the most common. Grease is composed of oil and a thickening agent to obtain its consistency, while the oil is what actually lubricates. Oils can be synthetic, vegetable or mineral-based as well as a combination of these.

What is the meaning of word horology?

1 : the science of measuring time. 2 : the art of making instruments for indicating time.

What is the meaning of STLE?

Rating. STLE. Society of Tribologists and Lubrication Engineers.

What is friction wear?

Conclusion. Friction is the force that occurs between two contact surfaces in relative motion, whereas wear is the phenomenon of mechanical and/or chemical damage that affects the quality of the materials in contact with each other.

Who initiated Nanotribology?

Direct observation of friction and wear at the nanoscale started with the first Scanning Tunneling Microscope (STM), which can obtain three-dimensional images of surfaces with atomic resolution; this instrument was developed by Gerd Binnig and Henrich Rohrer in 1981.

What is the study of friction called?

As a field of science, study of friction is part of tribology, once called “the most important subject no one has heard of”. Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear.

What is a hair trichologist?

A trichologist is a specialist who focuses on trichology — the study of diseases or problems related to the hair and scalp, as well as their treatments. Trichology takes its name from the Greek word Trikhos, which means hair.

What does boundary lubrication mean?

Boundary lubrication is perhaps best defined as the lubrication of surfaces by fluid films so thin that the friction coefficient is affected by both the type of lubricant and the nature of the surface, and is largely independent of viscosity.

What is boundary lubrication in an engine?

Boundary lubrication is defined as that in which the sliding surfaces are separated by a very thin molecular film of lubricant, so that the chemical and physical natures of the surfaces and the lubricant are of major importance.

What do you mean by hydrostatic lubrication?

Hydrostatic lubrication is characterized by the complete separation of the conjugated surfaces of a kinematic pair, by means of a film of fluid, which is pressurized by an external piece of equipment.

What is erosive wear?

Erosive wear can be defined as degradation of material due to impact of particles travelling with significant velocity. From: Developments in High Temperature Corrosion and Protection of Materials, 2008.

What is fatigue fracture wear?

Fatigue wear is a type of wear where a number of cycles is needed to generate debris. The fatigue process in metals may induce the generation of surface and subsurface cracks, which after a critical number of cycles results in a severe damage, such as large fragments leaving the surface.

What is surface fatigue?

Surface fatigue is a failure that occurs due to cyclic loading. Surface fatigue is different from other types of fatigue failures because it is found solely on the top layer of a material. Surface fatigue usually appears in the form of microcracks on a material’s surface.
