Nanoindenter

Nanoindentation testing, also referring to as Instrumented Indentation Testing (IIT) and Depth Sensing Indentation (DSI), is a technique for measuring the mechanical properties of materials.

Surface AnalysisNanoindenter G200

It is a development of traditional hardness tests such as Brinell, Rockwell, Vickers, and Knoop. Instrumented indentation testing is similar to traditional hardness testing in that a hard indenter, usually diamond, is pressed into contact with the test material.

Overview

The Keysight Nanoindenter G200, located at the Bernal institute, is a state-of-the-art indentation test that allows for the characterisation of nanoindentation properties over six orders of magnitude (from nanometers to millimeters).
• In addition to indentation, capabilities extended to do quantitative scratch and wear testing, probe-based imaging, expanded load capacity up to 10N, and customisable test protocols.
• Measurement of deformation The maximum load possible with the standard XP Indentation head is 500 mN and with the High Load option is 10 N, with a load resolution of 50 nN.
• Two sample stages are available; a standard G200 stage with useable surface area of 100mm x 100mm and positioning accuracy of 1μm; a Nanovision stage with useable surface area of 100μm x 100μm and positioning accuracy of <2nm.
