Scratch tester Heads
Multiple scratch heads can be bought on same platform. It takes less than 5 minutes to interchange the head (easy to exchange mechanism). This allows flexibility to do scratch at any range on same platform and using same software.
Module NS100 (for Nano scratch)
For Coating < 1000nm
  • Max Down Force 1000mN
Module MS100 (for Micro scratch)
For Coating < 5 Micron
  • Max Down Force 50N
Module HS100 (for Macro Scratch)
For Coating > 5 Micron
  • Max Down Force 200N
Inline Imaging
The sample automatically moves under optical profilometer and creates a 3D stitched image. The optical profilometer is specifically optimized for scratch test. The head allows to measure steep scratch slopes, transparent coatings (glass etc) and measure roughness, volume wear, method of failure etc. with sub nm resolution.

More information on Scratch tests
What is Scratch test?

Scratch test involves producing the scratches at progressively increasing or constant load on the test sample. The data allows to calculate adhesion and scratch hardness of sample. The test can be done using several standard tips( from few nm to several microns) or non standard sample (coins, nails, blades etc)

Scratch Adhesion

The test requires applying a progressive increasing load on the sample that needs to be tested with a spherical tip. During the process of applying the load the sample is moved at a constant velocity. During the test several parameters such as Friction (fx), Down force (Fz), Coefficient of friction (COF), displacement (Z), Acoustic emission (AE) etc. are measured insitu. Failure of coating is determined by change in one of several of the measured parameters mentioned above. Typically ASTM standards such as ASTM d7187, C1624, 7027-05, ISO 20502, ISO 1518 mentions monitoring COF to determine point of coating failure . The load range, choice of tip is determined by the coating thickness, application, surface roughness etc.

Scratch Hardness

The test requires moving a sharp tip at constant load on the surface that needs to be characterized and on the standard sample with known hardness. During the test several parameters such as Friction (fx), Down force (Fz), Coefficient of friction (COF), displacement (Z), Acoustic emission (AE) etc. are measured insitu. As per ASTM standards G171-03 Hardness of coating is determined by calculating the ratio of width of scratch track between the sample and standard sample. The sample automatically moves under imaging technique of choice (WLI, AFM, microscope) and creates a complete 3D image by stitching across entire track. The width of the track is calculated from this image. The load range, choice of tip is determined by the coating thickness, application, surface roughness etc.
