Hardness, английский
- Dureté
- A property of wood that enables it to resist indentation. it is measure in kn and is often determined by the janka hardness test.
- The resistance of a substance to surface abrasion.
- Твердость
- A property of wood that enables it to resist indentation.
- A diamond’s ability to resist scratches
- Generally measured using the mohs scale. resistance a material offers to scratching or abrasion.
- As used by individuals associated with the drilling and bit-setting industry, the relative ability of a mineral to scratch another mineral or to be penetrated by a knoop indenter; also, the relative ability of a metal to resist being penetrated by the indenter point of a vickers, brinnell, or eockwell hardness-testing apparatus.
- Твёрдость; жёсткость; стойкость ~ of water жёсткость воды
- 1. when used in reference to water, hardness is the total parts per million (ppm) of calcium an caco3 plus the magnesium expressed as equivalent caco3 [ppm hardness (as caco3) = (ppm ca x 2.497 + ppm mg x 4.116)]. 2. used in reference to pulp to denote the degree of delignification.
- Resistance of a material to indentation or scratching
- A measure of the ability of a material to withstand penetration by a hard pointed object. regarding thermal interface materials, this property is usually inversely proportional to the ability of a material to conform to uneven surfaces. hardness shore a (shore d, shore )
- Resistance of metal to plastic deformation, usually by indentation. however, the term may also refer to stiffness or temper or to resistance to scratching, abrasion, or cutting.
- In materials science, the resistance of a material to deformation, scratching, abrasion, or cutting. see also brinell hardness; rockwell hardness.
- Resistance of metal to denting, to plastic deformation by bending or to mechanical deformation by scratching, abrasion or cutting. typically measured by indentation.
