3. Superhard material - Wikipedia

   en.wikipedia.org/wiki/Superhard_material

   Diamond and graphite materials and structure. Diamond is an allotrope of carbon where the atoms are arranged in a modified version of face-centered cubic (fcc) structure known as "diamond cubic". It is known for its hardness (see table above) and incompressibility and is targeted for some potential optical and electrical applications.

4. Diamond-like carbon - Wikipedia

   en.wikipedia.org/wiki/Diamond-like_carbon

   As implied by the name, diamond-like carbon (DLC), the value of such coatings accrues from their ability to provide some of the properties of diamond to surfaces of almost any material. The primary desirable qualities are hardness, wear resistance, and slickness (DLC film friction coefficient against polished steel ranges from 0.05 to 0.20 [10]).

5. Amorphous carbon - Wikipedia

   en.wikipedia.org/wiki/Amorphous_carbon

   In mineralogy, amorphous carbon is the name used for coal, carbide-derived carbon, and other impure forms of carbon that are neither graphite nor diamond. In a crystallographic sense, however, the materials are not truly amorphous but rather polycrystalline materials of graphite or diamond [2] within an amorphous carbon matrix. Commercial ...

6. Carbonado - Wikipedia

   en.wikipedia.org/wiki/Carbonado

   Carbonado, commonly known as black diamond, is one of the toughest forms of natural diamond. It is an impure, high-density, micro-porous form of polycrystalline diamond consisting of diamond, graphite , and amorphous carbon , with minor crystalline precipitates filling pores and occasional reduced metal inclusions.

8. Material properties of diamond - Wikipedia

   en.wikipedia.org/wiki/Material_properties_of_diamond

   Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in structure. If heated over 700 °C (1,292 °F) in air, diamond, being a form of carbon, oxidizes and its surface blackens, but the surface can be restored by re-polishing. [ 47 ]

9. Anti-scratch coating - Wikipedia

   en.wikipedia.org/wiki/Anti-scratch_coating

   Optical coatings include diamond-like carbon (DLC) and anti-reflective-scratch hybrid coatings. Diamond-like Carbon is a coating that shares diamonds' extreme scratch resistance. Anti-reflective Scratch hybrid coatings contain scratch-resistant additives with anti-reflective coating materials. [4] [5]
