Scratch hardness refers to the hardness of a material in terms of resistance to scratches and abrasion by a harder material forcefully drawn over its surface. Scratch hardness test or scratch test refers to any of a number of methods of measuring scratch hardness. Resistance to abrasion is less affected by surface variations than indentation methods. Scratch hardness is measured with a sclerometer. WebMicro-scratch testing is commonly performed to evaluate the adherence of surface coatings. In one study, the adherence of functionally graded HA film on Si substrate and sputter-deposited film with 62% crystallinity on glass substrate were determined using a CSM Microscratch Instrument (MicroPhotonics, Irvine, CA, USA) [69].
