2. Anti-scratch coating - Wikipedia

   en.wikipedia.org/wiki/Anti-scratch_coating

   Anti-scratch coating is a type of protective coating or film applied to an object's surface for mitigation against scratches. Scratches are small surface-level cuts left on a surface following interaction with a sharper object. Anti-scratch coatings provide scratch resistances by containing tiny microscopic materials with scratch-resistant ...

3. Superhard material - Wikipedia

   en.wikipedia.org/wiki/Superhard_material

   It is unclear whether the synthesis products are diamond-like solid solutions between carbon and boron nitride or just mechanical mixtures of highly dispersed diamond and c-BN. In 2001, a diamond-like-structured c-BC 2 N was synthesized at pressures >18 GPa and temperatures >2,200 K by a direct solid-state phase transition of graphite-like (BN ...

4. Polished concrete - Wikipedia

   en.wikipedia.org/wiki/Polished_concrete

   A diamond polished concrete floor is time-consuming. Six to twelve steps of grinding may be needed. The general rule is to start the initial grinding with a coarse 30/60-grit diamond and finish with a 1600- or 3000+ grit diamond, depending on the exposure level of aggregate and gloss level required.

5. Diamond-like carbon - Wikipedia

   en.wikipedia.org/wiki/Diamond-like_carbon

   Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.

6. Black oxide - Wikipedia

   en.wikipedia.org/wiki/Black_oxide

   The surface finish is usually satin, but it can be turned glossy by coating in a clear high-gloss enamel. [8] On a microscopic scale dendrites form on the surface finish, which trap light and increase absorptivity. Because of this property the coating is used in aerospace, microscopy and other optical applications to minimise light reflection. [8]

7. Paint protection film - Wikipedia

   en.wikipedia.org/wiki/Paint_protection_film

   Paint protection film (PPF, also called clear bra, clear film or clear paint film) is a thermoplastic urethane often self-healing film applied to painted surfaces of a new or used car in order to protect the paint from stone chips, bug splatters, and minor abrasions. This film is also used on airplanes, RVs, cell phones, electronics, screens ...
