Abrasion Basics for Contamination Control

Clean Manufacturing Tutorial: "Abrasion Basics for Contamination Control". To minimize particles, understand abrasion.

Everyday experience shows that particles are generated by abrasion. Chalk dust, pencil “lead”
powder, particles due to the wear of bearings—all are familiar. Despite how commonplace wear
seems to be, however, the subject is actually quite complicated and still under active
investigation. Abrasion — the wearing away of one solid surface by another — is a common
source of contaminating particulate matter in clean manufacturing. Abrasion-generated particles
can be transported by gas, liquid, or solid-solid contact and result in significant damage to
products.
