Chrome coating for engine cylinder

[Flamefront]

I need to find a supplier who can plate a one-off engine cylinder for a prototype. The cylinder is aluminum (319) and I need a porous chrome plating on it to survive the piston ring running against it. An alternative is Nikaseal (sp), so any leads to a vendor for that would be helpful as well.

Thanks to all

Here are a couple of firms that specialize in chromium & Nikasil^TM plating of single & multiple cylinder bores:

Perhaps locate a local EAA chapter; DIY aircraft builders must know some good vendors.
