Lubrication is defined as follows:

• Lubrication is the application of a friction-reducing layer between moving surfaces in contact to reduce friction and wear.
• The lubricant can be in the form of a liquid, solid, or plastic.
• A lubricant is a material that is put between two surfaces in contact to minimise friction.
• To lubricate a surface, a variety of chemicals can be utilised. The most common are oil and grease.
