Hardness testing is a process used to measure the resistance of a material to deformation, indentation, or penetration. Hardness is a measure of the material’s ability to withstand external forces, such as wear, abrasion, and erosion. Hardness testing is commonly used to evaluate the mechanical properties of metals, alloys, and…

Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation.

More simply put, when using a fixed force (load)* and a given indenter, the smaller the indentation, the harder the material. Indentation…
