Understanding Abrasive Wear And How To Reduce It
Essentially, surface particles can be removed by this action, the action being referred to as "abrasion" or abrasive wear. The surface is, simply put, worn away. Abrasive wear can be affected by a number of factors including the following: The characteristics of motion. Regarding the material moving across the surface – abrasion properties.
