We measure the hardness of metal by using the Vickers hardness test, which provides accurate and reliable results.
A square base, pyramid-shaped diamond is used for testing, and loads are typically very light. Microhardness methods are suitable for testing metals, ceramics, composites, and almost any other type of material. Hardness is defined as the resistance to indentation and determined by measuring the permanent depth of the indentation. As a rule, the smaller the indentation left in the metal, the harder the metal.
To provide accurate results, we ensure that the surface of the specimen is smooth in order to permit a regular indentation shape and good measurement, and the test sample is always held perpendicular to the indenter.
The samples prepared at CBE+ Laboratories are mounted into a plastic medium which enables us to facilitate effective preparation and accurate testing. We also ensure that the indentations made are as large as possible to maximise the resolution of the measurement.
The specification for hardness testing is ASTM E384.
