Indentation & Scratch Tester SMT-5000

The Surface Mechanical Tester SMT-5000 is a versatile instrument. It merges the ability to measure mechanical properties, such as hardness, modulus, scratch adhesion, film thickness, in addition to surface roughness and many others. All this power is consolidated in one single platform. To that end, the IST module provides both indentation and scratch. Combining piezo actuation and capacitive sensing technologies, the IST brings the highest precision measurements from nano to micro ranges.

Besides the IST module, the SMT 5000 incorporates spectral reflectance film thickness with 3D profilometry and environmental modules. All these capacities cater to demanding engineers and researchers in many fields.

Automatic Stitching of In-line 3D Images

Scratch Data Visualization. Complete failure analysis and correlation to scratch data.

The complete 3D image of the scratch is obtained via automatic post-test imaging. The critical loads are easily positioned on the 3D panorama. In addition to the critical loads, the typical measurements enabled by this 3D imaging include scratch volume, penetration, residual deformation, roughness, and volume wear.

Load Profile and Custom Motions

Load Profiles: constant, linear or user defined load profiles. The applied normal force and resulting friction forces measured using precise NIST traceable sensors.
