2. Powder coating - Wikipedia

   en.wikipedia.org/wiki/Powder_coating

   Heat-sensitive carbon fiber tubes coated with a UV curable powder coating. Powder coating is a type of coating that is applied as a free-flowing, dry powder.Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.

3. Passivation (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Passivation_(chemistry)

   In physical chemistry and engineering, passivation is coating a material so that it becomes "passive", that is, less readily affected or corroded by the environment. . Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation

4. Fusion bonded epoxy coating - Wikipedia

   en.wikipedia.org/wiki/Fusion_bonded_epoxy_coating

   The molten powder ‘flows’ into the profile and bonds with the steel. The molten powder will become a solid coating, when the ‘gel time’ is over, which usually occurs within few seconds after coating application. The resin part of coating will undergo cross-linking, which is known as “curing” under the hot condition.

5. Thermal spraying - Wikipedia

   en.wikipedia.org/wiki/Thermal_spraying

   A powder feed stock is injected into the gas stream, which accelerates the powder up to 800 m/s. The stream of hot gas and powder is directed towards the surface to be coated. The powder partially melts in the stream, and deposits upon the substrate. The resulting coating has low porosity and high bond strength. [1]

6. Physical vapor deposition - Wikipedia

   en.wikipedia.org/wiki/Physical_vapor_deposition

   Most coatings have high temperature and good impact strength, excellent abrasion resistance and are so durable that protective topcoats are rarely necessary. PVD coatings have the ability to utilize virtually any type of inorganic and some organic coating materials on an equally diverse group of substrates and surfaces using a wide variety of ...

7. Detonation spraying - Wikipedia

   en.wikipedia.org/wiki/Detonation_spraying

   [citation needed] Many different mixtures of coating powders and D-gun settings can be used during detonation gun spraying of a material, all of which influence the final surface characteristics of the sprayed coating. Common powder materials used include but are not limited to: alumina-titania, alumina, tungsten carbide-tungsten-chromium ...
