3D Scratch Adhesion Tester UST-2 Overview
Main Features
- Nano, Micro, and Macro Scratch ranges on one platform
- 3D surface panorama image of each scratch
- Patented in-line 3D imaging of scratch
- Normal and tangential forces standard and measured atop the sample
- 3D Profiler and scratch data automatic correlation
Designed to quantify mechanical behaviors of bulk or coated surfaces in scratch. The UST-2 scratch tester measures scratch adhesion & cohesion, scratch hardness, mar resistance, and hardness. Additionally, the scratch tester provides multi-pass wear at nano, micro, and macro scale.
The In-line integrated 3D profiler allows a unique analysis of failures with high resolution. The profilometer correlates the effect of roughness, features, and more on the measured properties.
3D Scratch Tester Like No Other
Customizable To Fit Your Needs
Interchangeable Nano, Micro, Macro Scratch Measuring Modules
Down force from mN to 200 N (Higher force on MFT-5000 platform)
Patented In-line Profilometer
3D profiler to automatically combine high resolution nm profiler data and scratch test data
Lower Interchangeable Motions
Scratch in linear, rotary or custom motion.
XY Stage
High precision 210 mm XY stage to move test samples between testing and image positions, as well as performs slow speed reciprocating tests.
Upper Z Structure
High precision multiple Z drives with high resolution encoders to move position testing module and profilometer.
Platform
Open platform architecture for superior ease of use. Large sample testing volume, ability to mount and test any large dimension sample or full product.
Automatic Stitching Of In-line 3D Images
Scratch Data Visualization. Further analyze failure points and then relate to scratch data.
At the end of the scratch, the Universal Scratch Tester UST-2, automatically moves the sample under the optical profilometer to create a full 3D panorama of the scratch. The combination of the measuring head and the profilometer provide measurements for scratch volume, depth, residual deformation, roughness, volume wear and a clear determination of points of failure with sub-nanometer resolution. The turret on the profilometer allows the installation of up to 5 objectives providing multiple magnifications simultaneously.

Report
Automatic visualization for failures, adhesion, friction, cohesion and roughness characterizations. Residual depth, volume wear, and permanent deformation easily calculated.
Patented Integrated Four Mode Profilometer
The profilometer is optimized to image scratch and indentation marks with high resolutions. Automatic multiple imaging modes selection to image any sample surface – transparent, glass, mirror, rough, smooth, steep slope, and much more with ease.
Dark Field Mode
Allows detection of cracks at the surface with notable contrast
White Light Interferometer Mode
Allows high resolution images of flat surfaces
Spinning Disk Confocal Microscope Mode
Measures steep slopes, transparent, dark or rough surfaces
Bright Field Mode
2D profiles with high resolution and real colors
Load Profile and Custom Motions
Load Profiles: constant, linear increasing or decreasing, steps, or user’s defined load profiles. The applied normal force and resulting friction forces are measured using precise NIST traceable sensors with high thermal stability.
Various Motions: The automatic 210×150 mm XY stage can perform multiple scratch on single or multiple samples automatically. Scratch tests can be customize to achieve any motion profile –straight, curved, circle, zigzag, and more.
