Electrolysis nickel plated exhaust manifold

[jdub]

There's electroplating and there's electroless plating. One uses electricity while the other does not. I have no idea what electrolysis plating is but I suspect it refers to the first process

Tis true...LOL. I assumed he meant "electroless".

Umm... I always thought the process was called electroless nickle plating. I've never heard of electrolisis plating.

I've literally had tons of parts put through this process. and it can flake.

Only if the base surface is not prepared correctly. Any oxidation or oil and it will not bond correctly...that goes for both processes. Aluminum is more difficult to plate and requires additional chemical prep to make sure the plating will adhere properly. A rough (bead blasted) finish works better IMO. Personally, I think using that manifold is fine (I would) - keep in mind there is no thermal advantage using nickel vs what a ceramic coat would do.

yep, and that's why it can flake. I've found that the nickle adheres to hard materials much better than soft materials.
