Gouge hardness
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. WebDec 7, 2024 · Scope. 1.1 This test method covers laboratory procedures for determining the scratch hardness of the surfaces of solid materials.

Gouge hardness
Did you know?
Scratch hardness is the measure of how resistant a sample is to fracture or permanent plastic deformation due to friction from a sharp object. The principle is that an object made of a harder material will scratch an object made of a softer material. When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common test is Mohs scale, which is used in mineralogy. One tool to make this measurement is the sclerometer. WebJul 22, 2024 · Corrosionpedia Explains Scratch Hardness. Hardness is the resistance of a material to localized deformation.
