2. Superhard material - Wikipedia

   en.wikipedia.org/wiki/Superhard_material

   A superhard material is not necessarily "supertough". For example, the fracture toughness of diamond is about 7–10 MPa·m 1/2, [16] [17] which is high compared to other gemstones and ceramic materials, but poor compared to many metals and alloys – common steels and aluminium alloys have the toughness values at least 5 times higher. [18]

3. Synthetic diamond - Wikipedia

   en.wikipedia.org/wiki/Synthetic_diamond

   A laboratory-grown diamond (LGD), also called a lab-grown diamond, [ 1 ]laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is created through geological processes and obtained by mining).

4. Diamond-like carbon - Wikipedia

   en.wikipedia.org/wiki/Diamond-like_carbon

   A Co-alloy valve part from a producing oil well (30 mm diameter), coated on the right side with ta-C, in order to test for added resistance to chemical and abrasive degradation in the working environment. Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond.

5. Cubic zirconia - Wikipedia

   en.wikipedia.org/wiki/Cubic_zirconia

   The coating is thought to quench the excess fire of cubic zirconia, while improving its refractive index, thus making it appear more like diamond. Additionally, because of the high percentage of diamond bonds in the amorphous diamond coating, the finished simulant will show a positive diamond signature in Raman spectra.

6. Electrophoretic deposition - Wikipedia

   en.wikipedia.org/wiki/Electrophoretic_deposition

   Electrophoretic deposition (EPD), is a term for a broad range of industrial processes which includes electrocoating, cathodic electrodeposition, anodic electrodeposition, and electrophoretic coating, or electrophoretic painting. A characteristic feature of this process is that colloidal particles suspended in a liquid medium migrate under the ...

7. Titanium nitride - Wikipedia

   en.wikipedia.org/wiki/Titanium_nitride

   Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties. Applied as a thin coating, TiN is used to harden and protect cutting and sliding surfaces ...
