Hard chrome plating. Hard chrome, also known as industrial chrome or engineered chrome, is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include a broader set of conditions (such as oxidation resistance), and bulking ...

Thicker deposits, up to 1000 μm, are called hard chrome and are used in industrial equipment to reduce friction and wear. The traditional solution used for industrial hard chrome plating is made up of about 250 g/L of CrO 3 and about 2.5 g/L of SO 4 −. In solution, the chrome exists as chromic acid, known as hexavalent chromium. A high ...
Decorative chrome plating on a motorcycle. The high hardness and corrosion resistance of unalloyed chromium makes it a reliable metal for surface coating; it is still the most popular metal for sheet coating, with its above-average durability, compared to other coating metals. [75]
A variety of hardness-testing methods are available, including the Vickers, Brinell, Rockwell, Meyer and Leeb tests. Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels .
Cr 23 C 6 has a cubic crystal structure and a Vickers hardness of 976 kg/mm 2. [6] Cr 7 C 3 has a hexagonal crystal structure and a microhardness of 1336 kg/mm 2 . [ 6 ] Cr 3 C 2 is the most durable of the three compositions, and has an orthorhombic crystal structure with a microhardness of 2280 kg/mm 2 . [ 6 ]
Among the 14 people killed in the New Orleans attack: a warehouse manager, an account executive, an aspiring nurse and two loving parents.
The Brinell hardness is designated by the most commonly used test standards (ASTM E10-14 [2] and ISO 6506–1:2005) as HBW (H from hardness, B from brinell and W from the material of the indenter, tungsten (wolfram) carbide). In former standards HB or HBS were used to refer to measurements made with steel indenters.
