Additives – Antioxidants

February 11, 2024

For the prevention of lubricant oxidation, antioxidants are the key additive that protects the lubricant from oxidative degradation.

Additives – Detergents

February 18, 2024

Detergents enhance the lubricant ability to suspend the harmful products already formed in the bulk lubricant.

Read More

Additives – Dispersants

February 25, 2024

Dispersing soot and deposits is clearly the primary function of a dispersant. Dispersants need other properties to perform effectively.

Additives – Antiwear and Extreme Pressure

March 17, 2024

Antiwear and extreme pressure (EP) additives are added to lubricating oils to decrease wear and prevent seizure under such conditions.

Read More

Additives – Viscosity Index Improvers

March 24, 2024

Viscosity Index Improvers are high Mwt, oil-soluble polymers, which ideally provide increased viscosity at higher temperatures.

Additives – Pour Point Depressant

March 31, 2024

Pour point depressants (PPDs) are polymeric molecules that are added to mineral oil-based lubricants to improve their cold flow properties.

Read More

Additives – Corrosion Inhibitors

April 7, 2024

Corrosion is a chemical reaction between a metal and its environment, which produces a deterioration of the material properties.

Introduction to Friction

April 14, 2024

Friction is the gradual loss of kinetic energy in many situations where bodies move relative to one another. We concerned only with solid friction.

Read More

Types of Friction

April 21, 2024

Friction is categorized by the nature of the surfaces in contact and the conditions under which they are interacting.

Read More

Abrasive Wear

April 28, 2024

Abrasive wear is due to hard particles or hard protuberances forced against and moving along a solid surface.

Read More

Sliding and Adhesive Wear

May 05, 2024

Adhesive wear by transference of material from one surface to another during relative motion due to a process of solid-phase welding.

Read More

Fretting Wear

May 12, 2024

Fretting is the small-amplitude oscillatory movement that may occur between contacting surfaces, which are usually nominally at rest.

Read More

Friction and Wear of Engine Parts

May 19, 2024

The internal combustion engine is one of the most important types of engineering power plants. Friction and wear of engine affect engine performance.

Read More

Wear of Gears

May 26, 2024

A gearset must be designed with adequate strength, wear of gears resistance, and scuffing resistance. Lubricant choice and its application method are also important.
