Silver plating bimetals

Hello,

We need to silver plate a bimetal (Imphy 108SP), we noticed that we can't get good adhesion of the silver layer when it exceed 1.5-2micron thickness.

The guys at the plating shop (we don't have such capability in house) say they tested all solution unsuccessfully.

Can anyone tell me if a trick exists?

Hi.

Is not a trick but if the bimetal is stainless steel or copper nickel alloy is necesary have first nickel woods( Nickel chloride bath)for stainless and copper strike for copper alloys and if you don't have strike silver before plating bath probably you had lack of adhesion.

I hope this helps
