Wear Abrasion Test for Anodize


(2001)

Our customers are complaining of scratches on the sulfuric acid anodize surfaces of our lithographic printing plates. They are causing them by improper handling (plate on plate), but said they haven't had the problem in the past. Is there a way I can distinguish the scratch resistance on a variety of plates? I have tried an automated lateral abrasion tester (plate on plate)--too severe. Other abrading materials with the tester cannot discriminate between plates. Is there a better test method?

We have done a lot of measurements on soft and hard anodised aluminum substrates with our UST instrument. The UST instruments is measuring the scratch resistance and provides you with an exact number and also the variation of the scratch resistance along the surface.
