Nanoindentation tester

The Nano Scratch Tester is particularly suited for characterizing the scratch resistance and adhesion of thin films and coatings with a typical thickness below 1000 nm. Analyze organic and inorganic, as well as soft and hard coatings. The unique design of the nano-scratch measurement head includes two sensors for force and depth measurements associated with a state-of-the-art piezoelectric actuator – get results in milliseconds, plus great accuracy and great flexibility.

Mechanical Tester models come with true feedback load control from independent load and depth sensors that provide unmatched accuracy and the highest repeatability available on the market. This technology allows a user to perform Nanoindentation and Microindentation for Hardness and Elastic Modulus Testing, Stress vs Strain Analysis, Creep and Relaxation, Loss and Storage Modulus, Yield Strength and Fatigue, Fracture Toughness and Nano-scratch & Micro-scratch for Scratch Hardness Testing, Multi-pass Wear Test, Cohesive and Adhesive Failure Testing as well as Coefficient of Friction testing, all available on one system.

Full synchronized panorama for analysis whenever, wherever

This unique feature of our Nano Scratch Tester automatically synchronizes the panoramic image of the whole scratch in perfect focus with scratch data from all sensors. Perform critical loads analysis based on panorama observation and signal recordings at any time.

Fast small-force response

The Nano Scratch Tester incorporates a double cantilever beam for application of the load combined with a piezoelectric actuator for an ultra-fast response (within milliseconds) to the load applied. This concept also corrects the result for deviations caused by any event occurring during the scratch (e.g. appearance of cracks and failure, defects, or non-flat sample).

Apply exactly the force you want

The closed active force feedback loop provides even more accurate nano scratch testing (normal load resolution of 0.01 µN and noise floor of 0.1 µNm). incorporates a real sensor for force measurement that directly feeds back to the normal force actuator. This ensures reproducible scratch testing, even when you investigate more complex surface geometries like non-parallel, rough, or curved samples.

Elastic recovery studies: True penetration depth measurements

Nano Scratch Tester incorporates a real displacement sensor for monitoring the vertical motion of the indenter. The unique technique of pre- and post-scan obtains the true depth: elastic, plastic, and viscoelastic properties of materials can therefore be evaluated. This technique involves a pre-scan recording of the surface profile (form, waviness, and roughness) of the sample before the scratch test. NST³ corrects the indenter depth during the scratch (penetration depth) and after the scratch (residual depth) using the surface profile.

Multi-post-scan mode to measure viscous behavior after a scratch

After a scratch, you can define unlimited post-scan measurements in the software with a delta in time to measure the residual depth. This new analysis will give you additional understanding of the deformation behavior of your surface versus the recovery time.
