I've had a lot of questions on Cr VI. It has been hard to find a source of information on how Cr VI relates to zinc (?) chromate platings. How much Cr VI is typically found when it is used in a plating? What is the difference between Cr VI and Cr III? Why does Cr VI produce a better passivation plating? Etc, etc.
So does anyone know where we can find a Cr VI (and III) "101" primer?
