Hardness test: A test designed to assess the resistance to penetration from a load. Typically used a quality control test for thermal spray coatings.
A test used to determine the relative resistance to indentation or displacement of metals by pressure, or by resistance to abrasion. Common methods of testing include Brinell, Rockwell, and Vickers tests.
A test to measure a particular material's resistance to indentation. Tests for sheet metal include Rockwell, Rockwell Superficial, Tukon and Vickers.
A test to measure the resistance to indentation of a material. Test for sheet metal include Rockwell, Rockwell Superficial, Tukon and Vickers.
Hardness testing consists of pressing an indenter into a flat surface under a perfectly controlled load, then measuring the dimension of the resulting indentation. The three methods most commonly used for stainless steel are the Rockwell B, Rockwell C and Vickers tests. The higher the number, the harder the material.
A test designed to assess the resistance to penetration from a load. The surface is indented under a defined load and the depth of penetration is observed.
Any of several arbitrary methods for determining the hardness of metals. Usually an indentation is made under specified conditions and the hardness is indicated by the diameter (Brinell hardness) or the depth (Rockwell hardness) of the indentation.
