Letter 40093 Haze in Chrome LCD areas [Arizona]  March 28, 2006 Hello all: I appreciate any help given.... I am having a problem with my chrome giving off a haze in the LCD areas. It is a standard Hex bath with no additives 33 oz chromic acid .33 sulfuric Water Fume blanket Chrome plating is preceded by standard bright watts nickel. I have tried varying the temp from 110 to 120 and get the same results. When I turn up the power to the point of making the haze dissapear I start to get a slight burning on the edges. It does not matter the base metal as it happens with everything from steel to zinc die castings. I have sent samples out of both the nickel and chrome and am awaiting analysis.

Thank you,

Tom, sorry I can't be of any help with your question, but the texture on the part shown in the photo is interesting, did you make the part?

Lawrence:
The parts are from a early 1900s KOKER barber chair.
They are the "legs" that go from the arms down to the footplate.

Just a shot in the dark but have you checked for any zinc contamination in your chrome AND nickel bath in ppm?

I have had High Iron in my chrome bath lower my effency of my chrome bath. and cause the same problem, One source or either zn, cu, or fe could be parts in the bottom of your tank.

Hello,
It looks like you have some passive nickel or your chrome bath doesn't activate enough. Try a mixed catalyst bath.

I finally got it all fixed. :)
My leveler was very low in one bath and gone in the other in my nickel. I has also learned that I should use a ratio of 5:1 brightner/leveler when making adds to the nickel bath. (I use a lot of aux. anodes for restoration work and it was killing my leveler)
I also needed more current in the chrome.
So......all is well now
Thanks!
