That's just what a search turned up. From memory Porsche used a nickel-silver alloy to match the heat expansion of the cylinder to the piston (or vice versa), but DuckDuckGo doesn't support the contention.
What I found interesting was that chemical deposition is more uniform than electro-plating. I suspect that's because electroplating is sensitive to the placement of the anode.
