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...

1. Yes, "yellow chromated" and "yellow passivated" are the same -- meaning an electroplated finish (usually zinc plating because it's the least expensive) followed by a chromate conversion coating which shall be yellow in color. 2. "Black finish" doesn't imply anything except the color. B...

zinc plating nearly always receives a 'chromate conversion coating'. This involves a dip in a solution containing chromates and/or dichromates which may be optimized to impart a yellow color or to remain clear (other colors like olive or black are less common). But whether the species in th...
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...
