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, 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)
