Hardness. Hardness is the resistance of a material to localized deformation. The term can apply to deformation from indentation, scratching, cutting or bending. In metals, ceramics and most polymers, the deformation considered is plastic deformation of the surface.

Surface hardness was measured using a Clegg Impact Soil Tester (CIST) equipped with a 2.25 kg (5 lb) missile and a drop height of 455 mm (American Society for Testing and Materials, 2000b) and the F355 method equipped with a 9.1 kg (20 lb) missile and a drop height of 610 mm (American Society for Testing and Materials, 2000a) (Fig 15).

SHD – Surface Hardness Depth – Curve Measurements

Surface hardening is a heat treatment process that does not change the chemical composition of the surface layer, in contrast to nitriding and case hardening, for example. The aim of surface hardening is to achieve a completely martensitic structure in the surface layer and leave the remaining cross-section in its original condition.

Surface hardening, treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering because it can withstand very high stress and fatigue, a property that is required in such items as gears and anti-friction bearings.

Case-hardening - Wikipedia
Case-hardening - Wikipedia

Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal at the surface. For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen into the surface layer. Case …

Measuring Surface Hardness Surface hardness is measured by determining the ‘Gmax’ of the playing surface. Gmax is a numerical value representing the hardness of the surface, with higher values indicating a harder surface. The Clegg Impact Soil Tester is the device most commonly used to measure Gmax on natural turf fields. This
