2. Bluing (steel) - Wikipedia

   en.wikipedia.org/wiki/Bluing_(steel)

   Bluing, sometimes spelled as blueing, is a passivation process in which steel is partially protected against rust using a black oxide coating. It is named after the blue-black appearance of the resulting protective finish. Bluing involves an electrochemical conversion coating resulting from an oxidizing chemical reaction with iron on the ...

3. Fusion bonded epoxy coating - Wikipedia

   en.wikipedia.org/wiki/Fusion_bonded_epoxy_coating

   Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy -based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars (though being phased out as of 2005 [1]) and on a wide ...

4. Phosphate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Phosphate_conversion_coating

   Phosphate conversion coating. Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1][2][3] It is one of the most common types of conversion ...

5. Seasoning (cookware) - Wikipedia

   en.wikipedia.org/wiki/Seasoning_(cookware)

   Seasoning (cookware) Seasoning is the process of coating the surface of cookware with fat which is heated in order to produce a corrosion resistant layer of polymerized fat. [1][2] It is required for raw cast-iron cookware [3] and carbon steel, which otherwise rust rapidly in use, but is also used for many other types of cookware.

6. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Cathodic protection (CP; / kæˈθɒdɪk / ⓘ) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. [1] A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode. The sacrificial metal then corrodes instead ...

7. Galvanization - Wikipedia

   en.wikipedia.org/wiki/Galvanization

   Galvanization. Galvanized surface with visible spangle. Galvanization or galvanizing (also spelled galvanisation or galvanising) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten ...

8. Passivation (chemistry) - Wikipedia

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

   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 in the air. As a technique, passivation is the use of a light coat of a protective material, such as metal oxide, to create a shield against ...

9. Black oxide - Wikipedia

   en.wikipedia.org/wiki/Black_oxide

   Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. [ 1 ] It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. [ 2 ] To achieve maximal corrosion resistance the black oxide must be impregnated ...
