Scratch Tester

Specifications:

• Generation of scratches on the sample by drawing a diamond stylus across the surface, while applying a continuously increasing load.
• Identification of the load at which the coating flakes off by acoustic emission signals.
• Possibility of wide range of load (0-200 N) application.
• Movement of the specimen holder at desired velocity (1-100 mm/min).
• Possibility of specimen holder movement along x and y axis.
• Possibility of following the scratch that is generated on the specimen from the monitor.
• Ability to transfer the image by CCD camera to the compter.
• Possibility to apply the load with desired rate.

Applications:

• Measurement of the adhesion strength of hard coatings on the substrates.
