Scratch Resistance Test
Scratch Resistance is the property of a substance that is resistant to repeated rubbing or scratching. In general, it meant the resistance of a (coating) layer or surface against mechanical friction.
Scratch testing is carried out to get an insight into materials to determine the resistance to abrasion and wear of modern composite materials and automotive paints varnishes, as well as coatings. Scratch testing is a simple and rapid method of characterizing coatings, but results obtained are influenced by various factors such as coating thickness, substrate mechanical properties, interfacial bond strength, and test conditions such as scratch speed, load, and indenter tip radius.
A range of conical diamond tips (apical angle from 35° to 150°) are drawn across the surface under constant, stepwise or progressively increasing load.
The morphology of the scratches is examined with a combination of microscopy and profilometry techniques. Scratch hardness values are calculated to generate a scratch map that depicts the behavior of the surface under a complete range of working conditions.
