microhardness

Microhardness is a measure of how resistant a material is to indentation or scratching when a very small force is applied. It helps assess the material's surface strength and durability at a tiny scale, often used for testing thin coatings or small components. The process involves pressing a tiny diamond or other indenter into the surface and measuring the size of the indentation; the smaller the indentation for a given force, the harder the material. Microhardness tests provide detailed information about surface properties essential for quality control and material selection.
