Definition: Abrasive means "to make abrasive" or "to produce a hard, rough substance," in chemistry. Abrasion causes material to lose its original smoothness, as it erodes away the surface layer with every impact. One kind of abrasive material used in manufacturing is a sandblaster. Sandblasting is a process that uses high pressure and heat to create a rough surface on materials by removing them one grain at a time using a sandblaster or abrasive stone. Abrasive materials are often used in metalworking, painting, and other applications where the need for a rough finish is urgent.
