Seeking Chrome-6-free Zinc Cobalt Plating Service
We require a plating process to exceed 480 hours salt spray following a 160 °C bake for 2 hours. However this process must not contain Chrome 6.
One solution offered by a company in France was Zinc Cobalt but I have not been able to find a contractor in the UK to plate these steel components.
Any suggestions on contractors for Zinc Cobalt or alternative plating that conforms to BMW's "Black" list (prohibited substances)Mr. Jones
Dear Mr Jones,
The way to meet the spec is to use Zinc- iron with a triavalent Black Chromate. I have word from Surtec Gmbh, that they have a Triavalent Black Chromate available.
