Pin-on-Disk grinding test:Pin-on-Disk grinding test

With ball on disk type friction abrasion testing equipment, I measured frictional force and quantity of abrasion.
The quantity of ratio abrasion calculated it by the abrasion volume method.
I compared the quantity of combinatorial ratio abrasion of each material.v
