Abrade
To grind or roughen up a surface by rubbing.
Abrasion
The action of removing some of the surface through rubbing friction.
Abrasion hardness
The ability of something (e.g., metal, ceramic) to resist abrasion.
Abrasive
A hard grit used for sanding or grinding. Usually a powder e.g., silicon carbide powder.

Bonded abrasive
Coated abrasive
Non-woven abrasive
Abrasive blast cleaning
In order to clean steel or remove rust from iron or scale from metal, sand or some other powder substance is forced by air pressure through a Nozzle. In this way the small particles of abrasive can penetrate the metal where sanding with sandpaper cannot. Also, very small craters are formed on the surface of the metal from the blasting action. When thoroughly cleaned the metal is ready for painting. Paint adheres better to these craters and imperfections than to a perfectly smooth surface.
Abrasive cleaner
A cleaning paste with some hard grit. It is used to remove the grime and oils from a surface or from your hands.
Abrasive disc
abrasive disc

Abrasive disc

A circular plate (often made of plastic with hard grit embedded into it) used for grinding or sanding.
Abrasive paper
Sandpaper (a paper upon which sand or hard grit has been glued) used for sanding or grinding.
