Nanoindentation for Thin Film < 100 nm

Strengths of nanoindentation test

1. Quick and easy measurement of a wide variety of materials. 
2. Determination of many mechanical properties. 
3. The preparation of samples is easy. 
4. Films thicker than 10 nm can be tested.
5. Determination of local properties of homogeneous as well as heterogeneous materials.
6. Fewer samples are required. 
7. Nanoindentation does not require a powerful microscope to measure the impression of the indentation

Limitations nanoindentation test

1. Pile up and sink in on the edges of the indent during indentation. 
2. Limited to linear, isotropic materials.
3. It is challenging to test soft materials. 
4. The interpretation of the result is difficult because the elastic modulus is tip-dependent. 
5. It is difficult to test materials with rough surfaces.

Uses of nanoindentation test

Nanoindentation is used to determine the mechanical properties of the microstructure of a wide range of materials. It is used to characterize thin films in electronics, and coatings for thermal barriers. It is also used to determine viscoelastic properties, microhardness, and scratch and wear resistance of different products.
