Default Flat Tappet, Cast Core Camshaft Coating ?

It has been a while since I had this done to my previous camshaft.
In 2008, I purchased a set of coated tool steel lifters from a company in North Carolina ( if I remember correctly ). At that same time, I sent them my new camshaft, along with related valve train parts, for them to do a test of sorts, to determine spring requirements, and make note of any concerns. I honestly don't know if that was done, but at that time, they suggested a coating / treatment of my camshaft.
Here is a photo of it:

It has kind of a polished aluminum look to it, and is very smooth. The cam was run with about 230 llb seat / 475 lb open pressures, and still shows no sign of use.
I like it.
Unfortunately, that intake lobe could not be controlled, so, I now have a new cam. This one has no special treatments. Because of the rather impressive durability of the previous camshaft... I think I would like to do this again.
So, my question is...
Can somebody help identify what this coating / treatment is, and possibly guide me to where I can get it done again ?
