Micro hardness Testing is a method of determining a material’s hardness or resistance to penetration when test samples are very small or thin, or when small regions in a composite sample or plating are to be measured. It can provide precise and detailed information about surface features of materials that have a fine microstructure, are multi-phase, non-homogeneous, or prone to cracking.

Microscopic imaging systems are critical to an array of biochemistry, life sciences, and general materials research applications. Prior to the development of the compound microscope, it was impossible to observe fundamental properties that now underlie our comprehension of physical matter.

Types of Micro Hardness

Brinell Hardness Test

During this test, an accurately controlled force is maintained when an indenter, generally a carbide ball, is forced into the test model for a specific period of time. Upon removal, it leaves an encircling indentation, the measurement of which is taken to calculate material hardness as per the formula.

Rockwell Hardness Test

There is also a Superficial Rockwell, along with a Rockwell Hardness Test. For each individual test, a little load is forced to either a steel ball or diamond cone indenter located on the surface of the test material to set up a zero reference point. This is followed by applying the main load for a specific period of time, with the minor load applied on releasing. The hardness number is the variation in deepness between the shift due to major load and the zero reference position.

Knoop Hardness Test

This Micro hardness Test is employed on miniature material features that cannot be put on test by other methods. It uses a testing load of 1 Kg or less. Just like the Brinell hardness test, the Knoop is performed by applying force to an indenter in a rhombus-shape over a period of time. Meticulous measurement of the impression is done and is employed alongside test load for calculation of value on the scale.

Vickers Hardness Test

With a maximum test load of 50 kg, the Vickers Hardness Test can be performed on both the macro and micro hardness scales. This sort of test is done by putting controlled force to an indenter over a period of time, which is a square-shaped diamond pyramid. The test load and impression measurement are employed with the required formula for calculating Vickers hardness value. Like Knoop and Brinell, this test has a scale that takes care of the entire range.
