Zinc plating for 400 hours of salt spray test  

++++

I am looking for information on zinc plating that will pass 400 hours of salt spray testing.

Maybe it would be easier to look for salt fog cabinets that allow your current zinc plating to survive for 400 hours :-)

Sorry, Arvind, just a joke based on a discussion last year. Must this be straight zinc or can it be a zinc alloy? Hexavalent chromates permitted? Barrel or rack? What material is the substrate? Please flesh out your inquiry with some detail. Thanks!

Your requirement of Salt Spray 400 hrs not specified whether white rust or red rust, in any case Zinc Alloy Plating with Iron or Cobalt in alkaline process is very much suitable. Depending upon the requirement of Chromate colour, you have to select the above process. Chromate may be hexavalent or Trivalent. I have got experience in achieving 400 hrs salt spray with the above process.

I want to meet 400 hrs of salt spray test using a trivalent plating without sealant. Currently we are using hexavalent plating. Has anybody achieved this without a sealant. I am interested to know more about this.

Arvind,

If you need 400 Hrs I suggest Zinc Iron Alkaline bath Plating followed by Trivalent Light Green Chromate which will exceed the 400 Hrs. The chemistries are available in India from Proprietary makers.
