NANO SCRATCH | ADHESION TESTING

Nano Scratch Adhesion Testing exploits a normal force range 10μN to 1600mN which is highly recommended for adhesion failure studies of thin films. With a long scratch path and very quick piezo speed load control, Nano Scratch Adhesion Testing is an important tool for the study of crack initiating and marring applications on all kinds of polymers such as varnish clearcoats used in the automobile industry.

Process:
During Nano Scratch Adhesion Testing, a sharp metal tip or a Rockwell C diamond is drawn across the coated surface with an increasing load, resulting in various types of failure at specific critical loads. Nano Scratch Adhesion Testing indentifies critical loads optically using a built-in video microscope. Once known, these critical loads are used to quantify the adhesive and cohesive properties of different film/substrate combinations. Additionally, failure points can be determined by using frictional force, optional acoustic emission and depth measurement. These parameters constitute a unique signature of the
coating/substrate system.
