Scratch Testers RSS Feed - Scratch Testers

Scratch testers are used to determine the adhesion strength of coatings to substrates. They work by moving a hard indenter (typically diamond) across the surface of a sample. As the indenter travels across the surface the load in gradually increased. At a critical load the coating will fail by chipping or delaminating.

Featured Equipment
The new NanoTest Vantage system from Micro Materials Ltd offers a range of mechanical tests on the nano-scale, allowing the researcher to build a complete picture of material performance. The nanotest Vantage can characterise you samples using numerous techniques including nanoindentation, nano-impact and fatigue, nano-scratch and wear and nano-fretting.
Other Equipment
Anton Paar offers the Nano Scratch Tester (NST), which has been designed specifically for characterizing practical adhesion failure of thin films and coatings with a thickness less than 800nm.
The K93000 Scratch Tester is used to test the scratch resistance of flat solid surfaces such as coatings, metals, ceramics, composites, polymers, and other material surfaces.
The Micro Combi Tester integrates all the features of the Micro Indentation Tester and the Micro Scratch Tester from Anton Paar.
The Micro Scratch Tester (MST) is used for defining the precise characterization of the adhesion failure of thin films and coatings with a typical thickness of less than 5µm.
The Revetest®, Macro Scratch Tester (RST) is regarded worldwide as the paradigm system for the characterization of hard-coated materials with a coating thickness of several microns.
The REVETEST Xpress is the cost effective solution dedicated to Industrial and Quality Control (QC) applications. The Xpress provides measurement of adhesion, hardness and scratch resistance with a very user-friendly interface.
