Toughest Surface Finish?
Glavanising
Anodising
Nickel-Plating
Chroming
Powder-Coating
Epoxy Mastic
What say you????

My tuppence worth!
Wishbones on some of the Drakart's I race against are chromed and this seems exceptional durable when compared with other finishes such as my
powder coated ones. We race on a mix of tarmac and shale so the wishbones are continually peppered with stones. Its pretty remarkable how nice they
stay!

Chrome plating is porous and can peel of in sheets if moisture gets in. To prevent this parts are usually nickel plated then chromed. There is no
point in having your parts plated twice so I would go for nickel if I were to choose between those two.

Chroming is but the tougher the more britle it is. so powder coating it the best i would say or stainless 304 grade will last forever if you can get
it made in the shapes you need and looks great.

I'm no expert but many years ago I seem to recall Lotus chrome plated some of their suspension components and had problems because it masked any
stress cracks / welding faults that started to develop.
Lotus used to build everything very lightly so this may not be a problem on a "normal" car.
Just my thoughts!

Toughest finish?
Depleted uranium.
Tough enough to get the lump of anti-personnel explosive inside an anti-tank missile through the side of a tank. 
Hope that helps,

Depleted uranium.
Depleted uranium or U-238 has an atomic mass of 238. Its half-life is 4.468 billion years. It's natural occurrence is 2.1 parts per million.
Uranium is silver white, lustrous, malleable, ductile, and pyrophoric. This makes DU an ideal metal for use as kinetic energy penetrators,
counterweights, and shielding or armor. High density and pyrophoric (catches fire) nature are the two most significant physical properties that guided
its selection for use as a kinetic energy penetrator.
I don't think we'll be using that then

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Define tough ? --- Chrome isn't tough it is very HARD
To a materials scincentist thoughness and hardness are conflicting mechanical properties.
