why graphite can act as a lubricant

Unlike oil or grease, graphite lubricants don’t have a sticky residue that can attract dust. They can withstand both hot and cold temperatures, and they will work even when wet to keep parts moving smoothly.

why graphite can act as a lubricant

Graphite is made up of layers of carbon atoms bonded together by weak Van der Waals forces in a hexagonal system. This structure creates a very slippery surface that allows the layers to slide over each other without much resistance.

Because the bonds between the sheets are weak, graphite shows lower shearing strength under friction force. This makes it a highly effective solid lubricant. It has become one of the traditional and primary solid lubricants.

Why Graphite can be mixed with solvents

When a fast-evaporating solvent is combined with graphite, it enables the powder to form a dry film that is easily removed from the surface without leaving an oily residue. This type of lubrication works well in tight spots where crystalline carbon can’t reach, and it lasts considerably longer than wet-film lubricants.

Why a spray-type lubricant is better than a powdered graphite lubricant

A spray-type lubricant can be applied to surfaces and allowed to set up before use, making the particles less likely to fall into cracks and crevices. They can also be wiped off quickly, reducing the potential for clogging. This is important because a contaminated surface can lead to serious damage to machinery or equipment.
