If your plating process is well done, and everything is thoroughly cleaned after, the level of Cr(III) or Cr(VI) remaining should be low enough to be inconsequential to health and the environment. Multiple questions should be broken in multiple items, but anyway, This information to raises the aspect, if the outer passivated layer should be expected to have only Cr(III), irrespective of the used tank constituents. The most upvoted answer has stated little risk if chrome plating procedure is carried out well.Īs new information the CHROME PLATINGANDCHROMIC ACID ANODIZING SURVEY strongly suggests that the term chrome plating, can be divided regarding the categories a) Tank process (Hard plating decorative chromic acid anodizing) and b) *Tank constituent(s) (Hexavalent chrome trivalent chrome). If permissible I would like to add that I am most interested in those risks of the base material being copper. One of the answers mentioned that "chrome plating", being understood as a general term, does not necessarily imply which material is being plated. Test to detect leachable Cr (VI) ions on virtually any solid surface.īoth giving reason to thing that the Cr (VI) might remain in worrisome amounts after the chrome plating. The screening method can be used to determine chromium(VI) inĪlso test kits for Cr(IV) sold online mention in their description to be Some internet resources, such as tests/detection procedures for Cr(IV) described here, mention Worrisome concentrations/amounts of Cr(IV), is there a primitive test to detect this? If it is possible that the chrome plated object could have hexvalent chromium) to be with the chrome plated this is possible do primitive test exist to detect product? Should I expect impurities or residuals of toxic forms (e.g. My naïve impression has been that after the chrome plating process is over, the product will have an additionally a more or less thick layer of native Cr. the chrome plating) or will they remain with the product? Since some chrome plating production processes generate hexavalent_chromium compounds, which are reportedly highly toxic/carcinogenic, I wonder:ĭo the hexavalent chromium substances only occur (temporarily) during the production process (i.e.
