Which is a good fully automatic 3D scratch tester

Overview

3D scratch testerThe use of advanced scratch heads and high-resolution 3D profilometers enables users to conduct standard scratch testing and automatically perform sub nanometer level 3D imaging before and after testing.

Scratch test is used to evaluate the adhesion and scratch resistance of coatings and solid surfaces. Test the scratch on the surface of the sample under controlled force, with the scratch head moving along the sample surface under increasing, constant, or stepped loads. By detecting signals such as friction, displacement, and acoustic emission, as well as utilizing 3D imaging technology to detect coating damage.

3D scratch testerIt can test transparent, non transparent, hard coatings, biomaterials, decorative coatings, fiber optic materials, etc., with a loading force range covering micrometer to macroscopic levels. The test results mainly include mechanical properties (adhesion, friction, wear resistance, critical load Lc1 Lc2 Lc3), 3D morphology (roughness, coating thickness, scratch volume, scratch depth, etc.).

Product Features

• Scratch head

Easy to replace scratch head, with a testing range covering nanometer to macroscopic levels. The selection of the scope depends on the actual application and customer needs, with ultra-high resolution and low noise. Rigid design and closed-loop control can provide precise load loading.

• Online morphology

The sample can be automatically moved to the imaging module (AFM/white light interferometry/confocal/optical microscope), and large scratches can be automatically stitched together to create a complete scratch image. It can measure steep scratch slopes, transparent coatings (such as glass), as well as roughness, wear volume, failure modes, etc., with sub nanometer resolution.

• Sensors and environmental chambers

The device provides a variety of sensors, including acoustic emission sensors, electrical contact resistance sensors, capacitive displacement sensors, potentiometers, etc; Provide temperature chambers, humidity chambers, etc.

• Execute multiple ASTM/ISO/DIN standards

Modular design, matching modules as needed to execute multiple standards.

ISO 20502、ISO 1518、 DIN EN1071-3、 ASTM C1624、 ASTM D7187、 ASTM D7027、 ASTM G171 等。
