Description
Nanoindentation is the technique for assessing the mechanical properties of materials at the nano/micro scale. Hardness is measured as the area of the contact at the maximum load and reduced modulus is calculated from the slope of the load-displacements graph obtained. The Young's modulus of the material can be calculated if the Poison's ratio of the material is known.

Available mode for use
Indentation : Used primarily for measuring hardness and reduced modulus. Scratch tests: For measuring coefficient of friction and adhesion. Nano-DMA: Measurement of the storage and loss moduli (primarily for polymers), CMX (Constant strain rate test) - Hardness as a function of contact depth. High temperature tests : Low load (<9.5 mN) Type of Tests that can be carried out: 1)Indentation A) Low load(< 9.5mN)(RT and High temperature) B) High load (<500mN)(RT) 2)Scratch (RT) A) Constant load/displacement scratch B) Ramp load/displacement scratch 3)Nano DMA (RT and High temperature) A) Dynamic load( Variable load at a fixed frequency. B) Dynamic Frequency (Variable frequency at fixed load) 4) High temperature (Low load <9.5 mN)

Application

Bulk materials Multiphase materials MEMS devices-cantilever bending experiments to measure the stiffness, electrical experiments for cantilever bending experiments. Micropillar Experiments Nanostructured materials Scratch tests: A) Protective coatings B) Depth profiling of layered materials Biological materials Bone/Hair samples with proper sample preparation and polishing. Powder samples: Loose particles/powders cannot be done. Powder samples can only be done if pellet is made of the powder using a binder followed by sintering. (Dimensions of pellet- diameter of 10mm and height not more than 5mm). After the application of the load by the indenter, the pellet should not release the particles. Such samples would not be done as it can damage the indenter. Proper polishing of the pellet mounted sample has to be done.
