Codeposition of Teflon in a Nickel bath

Could you be able to do a search in your data base about the co-deposition of Teflon onto stainless steel using a nickel bath. I want to coat the stainless steel with a dielectric material. This dielectric material must be acid sulfuric acid resistant (15-20%) at 65 °C.

Thanks,

I don't think it will be dielectric. You can contact General Magnaplate [Linden, NJ], or Michael Feldstein of Surface Technology [Trenton, NJ]. There is a company called Niflor or Nifluor that makes such a product, but I don't know offhand where they are located.

Could you please also find the exact name of "Niflor" or "Nifluor" and its fax or e-mail address. I'm eager to receive some info. on this technology. Could I clog it so I can obtain a dielectric coat? Could you please suggest any other technology. The dielectric material must be sulfuric acid resistant (15-20%) at 65 c.

Best regards,

I don't have any further contact info about Niflor (sp?), perhaps another reader does, or can suggest another brand name.

I don't quite understand why, if you're looking for a dielectric material, you would want nickel in it. Why not just teflon coat the stainless steel parts?

Niflor is a registered trade name of Fothergill & Harvey plc. I have no address, but I believe the are in England. I understand that the development work for Niflor was done by Norman Hay Engineered Surfaces, LTD located in Coventry, England. One of their commercial outlets was Montgomery Plating also located in Coventry. I'm sure you are aware that this process can be licensed. Last time I contacted these folks, Alex Clark was the product manager.

I agree with you, Niflor would probably make a poor dielectric material. The teflon composes about 15 - 25% of the coating, depending on deposition conditions. A thicker layer of teflon is left on the surface, which can be baked to flow into a thin homogeneous layer. I have no information on its performance as a dielectric in this state. Perhaps someone at Norman Hay does.

Hope this helps.

We presently use Niflor coating on aluminum for its low friction and wear resistance. I have a copy of the Niflor data sheet if you are interested.
