Such an indentation testing in which both load and the depth of penetration are in the microscale or lower. Nanoindentation is used extensively nowadays to engineer better materials, mechanical properties play a very critical role.
Nanoscale engineering makes materials lighter, stronger, cheaper, more recyclable.
Traditional hardness tester had large varying tips, with lower spatial resolution and gave us the average hardness value over the larger area. Whereas Nanoindenters use Berkovich Tip, which has a precise geometry and provides real-time data.
You can identify the properties like hardness and modulus with a single indent and the same tip will generate an in-situ 3D topographical image of the surface.
At Industron Nanotechnology we manufacture Nanoindenter called NG50 and help education, private industry, centralized research facilities with sample testing as well.
