Coating

Coating is a covering that is applied to an object. The aim of applying coatings is to improve surface properties of a bulk material usually referred to as a substrate. One can improve amongst others appearance, adhesion, wetability, corrosion resistance, wear resistance, scratch resistance, etc.. They may be applied as liquids, gases or solids.

Examples of coatings:

• Coating and printing processes
• Chemical vapor deposition and physical vapor deposition
• Conversion coating

* Anodizing

* Chromate conversion coating

* Plasma electrolytic oxidation

* Oxide (coating)

* Phosphate (coating)

• Detonation Coating
• Paint

* Enamel (paint)

*Powder coating

* Industrial coating

* Silicate mineral paint

* Fusion bonded epoxy coating (FBE coating)

• Pickled and oiled (P&O), a type of plate steel coating.
• Plasma coatings
• Plating

* Electroless plating

* Electrochemical plating

• Polymer coatings, such as Teflon
• Sputtered or vacuum deposited materials
• Enamel (vitreous)
