3D Scratch Testing on MFT-5000 Overview

Main Features:

3D Profiler and scratch data automatic correlation
Nano scratch, micro scratch, macro scratch on same tester
High repeatability because of rigid design
Automatic reports

The 3D Scratch Test module quantifies coating substrate systems. It measures scratch adhesion, scratch hardness, and marr resistance at nano, micro and macro scale. In-line integrated 3D profilometer allows to analyze failures with high resolution. The profilometer correlates effect of roughness, features, and more, on the measured properties. Advanced patented capacitive sensors measure force and penetration depth with resolution needed to differentiate coatings at any scale.

Coatings Adhesion, Scratch, and Mar Resistance

The scratch test quantifies adhesion and scratch hardness of coatings. With new deposition methods and technologies, thinner coatings are finding their way in every aspect of our life. Coatings are present on LCD displays, phones, cutting tools, gems, glass, automobiles, and medical devices. Quantitative coating adhesion scratch testing is a simple practical test that the MFT-5000 provides for comprehensive coating scratch testing evaluation.

A scratch test requires applying a load on the sample that needs testing with a spherical or custom tip. During load application, the sample moves at a constant velocity and several parameters such as Friction (Fx), Down force (Fz), Coefficient of friction (COF), displacement (Z), acoustic emission (AE), and temperature are measured in situ.
