What Does Abrading Mean?
This is the classification of processes that involve grinding and polishing of surfaces by the act of removing integral portions of the material substrate. It can be termed as the wearing off of the high levels of a material's surface by the use of friction. It is a process used for trueing and leveling the substrate surface during the finishing process.
Corrosionpedia Explains Abrading
The adhesive nature of the coating is affected by the surface finish of the substrate.To accomplish this, various physical, chemical and mechanical treatments are required to remove surface contamination, oil, greases, surface layers and improve adhesion. The most used mechanical surface pre-treatment processed it that of abrasion.
The mode of method of accomplishing abrading will depend on the type of surface modifications required and material. The main aim is to remove foreign materials or weak surface laitance and alter the surface profile. The tolerance of the process is to remove material not greater than 0.1 microns. This is different from other cutting tools because natural particles with sharp edges are used to perform the removal of material; it is more of a polishing procedure.
The methods used for abrading include:
- Abrasive blasting (wet or dry)
- Mechanical abrading (abrasive wheels and sandpaper)
