How to produce black Ni-PTFE finishing?(2001)
Need help on composite electroless Ni-PTFE plating on stainless steel, followed by a blackening chemical immersion. Always get uneven finishing when do in lab scale plating, i.e. beaker with magnetic stirrer. Do I need special agitation for the plating?
For the post-treatment, have tried using Nitric Acid(20% to 50%); or mixture of ammonium peroxidisulphate, sodium disulphate, iron(III) sulphate & ammonium thiocyanate, but both have adhesion problem or only brown finishing.LF, Loh
