Other Names for Conversion Coatings

Chromate Conversion is also known as Iridite, Alodine, Divercoat, and Chromicoat


Applications

Chromate Conversion is used for protection against:
  • Corrosion, painted or unpainted parts.
  • Corrosion where electrical resistance is required.


About Conversion Coatings

Chromate Conversion is a chemical immersion process. During the process, aluminum oxide and chromic oxide is produced in accordance with the conversion reaction.

Alodine is a trade name for chemical conversion coating of aluminum (more commonly known as chem film or chemical conversion). Because alodine and anodize sound alike.  Sometimes confusion can be made between the two coatings.  While both are conversion coatings chem film is much thinner than anodizing and is also created by immersion but without the use of any electrical current.  Chem films of which are commonly seen in gold or ROHS clear versions.  They provide a conductive coating and are normally used in conjunction with masking in anodized parts.  The added coating provide corrosion protection and also is an excellent base primer for painting.   Common military specification for chemical conversion coating is MIL-DTL-5541.
