Rtec 3D scratch tester equipment to study scratch adhesion, scratch hardness, scratch resistance at nano, micro and macro scale. Inline integrated 3D profiler allows to create 3D stitched images to comprehensively and conclusively characterize the coating failures. Advanced capacitive sensors allows to measure penetration depth with resolution needed to differentiate coatings that have similar properties.

Main Features

● Patented Inline 3D Profilometer

● Nano scratch, Micro scratch , Macro  scratch

● Optimised 3D profilometer at nm resolution for any surface

● Scratch Flat or curved surface

Profilometer - Stitched Automatic Inline 3D Image

The automatic scratch instrument  moves the test sample under optical profilometer and creates a 3D stitched image after the scratch automatically. 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. The profiler comes with 5 objective turret that allows to mount multiple magnification objective simultaneously.  The profiler head has multiple imaging modes to effectively characterize any sample.

Dark Field Mode - Allows to find scratch surface, look at defects and cracks with high contrast

White light interferometer Mode - Allows to image flat surfaces

Confocal Microscopy Mode - Allows to measure dark, rough, transparent Surfaces

Bright FIeld Mode- Allows to create 2d profiler with real colors

Load Profile and Custom Motions

Load Profile The coating scratch tester allows to do the scratch test adhesion at constant, linear or custom load profiles. The load range depends on the scratch head mounted (nano, micro or macro). The applied force and friction are measured using precise NIST traceable sensors with negligible thermal drift across wide temperature and humidity range.

XY Motion The XY stage allows it to create multiple scratch on one or multiple samples automatically. The stage also allows to do coating scratch test in any motion profile (straight, curved, circle, zigzag etc). Both X and Y motion are independently programmable. The stage is used to create scratch and also to position the samples under the profiler after the tests are done.

Interchangeable Range on Same Platform

Scratch tester machine is modular and allows to easily change the scratch head to accommodate nano scratch, micro scratch and macro scratch on same platform. This testing method allows to measure adhesion strength, critical loads, hardness etc. of both thin films and thick coatings. The scratch test machine also allows to mount various kind of diamond tip. The choice of tip depends on the coating thickness and the coating substrate. Few commonly used tips are Rockwell diamond tip, 12.5 micron, tungsten carbide blade etc.

Sensors, Chambers

Sensors Various sensors on coating scratch adhesion tester allows to gather more information during the test.

Acoustic Emission - measures sound signal during the scratch, that may point to onset of coating failures.

Electrical Contact Resistance allows to measure point of coating failure by looking at resistance change during the scratch. 

Potentiostat allows to do scratch corrosion studies.
