K93000 Scratch Tester
The scratch tester is used to test the scratch resistance of flat solid surfaces such as coatings, metals, ceramics, composites, polymers, and other material surfaces. The test is performed by sliding a stylus over the surface of the test specimen. The normal load, sliding speed, direction, stylus geometry, and stylus material can be varied.

The resultant tangential force at the contact interface can be monitored using TriboDATA, the supplied Windows-based Data Acquisition Software. The onset of scratch or adhesion failure of coatings can be inferred from this data. A CCD camera is built-in to capture the scratch scar image.
