Yellow chromate conversion coatings on zinc have been investigated by electrochemical techniques such as emf measurements, current-potential characteristics and polarisation methods. A polarisation technique provides a rapid method for judging the corrosion protection offered by a conversion coating....
My company uses CRS withASTM B633zinc plating with yellow chromate conversion coating extensively in out products. Our products can and will be installed in various climates including close proximity to the ocean or salted highways and the corrosion protection given by the yellow chromate does not a...

thin, reliable corrosion fighting coating for steel parts. But zinc plating itself has a strong tendency to quickly get 'white rust'. To prevent that, zinc plating nearly always receives a 'chromate conversion coating'. This involves a dip in a solution containing chromates and/or dichromates ...
The overall quality of the coating system is largely dependent on the type and quality of the pre-treatment. The recommended types of pre-treatment for the most frequently used substrates are: Aluminium Chromate conversion Steel Zinc phosphate Zinc coated stee...

Zinc plating virtually always needs & receives a subsequent "chromate conversion coating" (sometimes called 'passivation') to deter white rust. In the 'old days', pre-1990s, there were two types: 1. a very robust hexavalent chromate which was usually yellow/golden. Hexavalent chromate is inhere...
A.Hi, Shawn. The gold or yellow color is the inherent color of hexavalent chromium so, traditionally, the yellow color implied more chrome and more corrosion protection. In these days of RoHS, most chromate conversion coating is actually trivalent, and any yellow color is just dye. ...
You'd have to go back about 50 years for the derivation of the trade name Iridite but I doubt that it has anything at all to do with Iridium. Iridite is a Macdermid trade name for chemicals for chromate conversion coating, which can also be called yellow dichromating. It's a scotch ...
"Yellow zinc plating" means zinc plating followed by a yellow chromate conversion coating. The process may be done in plating barrels or by racking the individual parts, and usually involves cleaning, activating, zinc plating, chromate conversion coating, and drying -- with good rinsing between ea...
