I was thinking about clear hard anodizing, then powder coating the flat part black. If you know anything about these processes and can offer some advise, or just feel like doing a little research I would greatly appreciate it.

I used to be the lab manager for a metal finishing company, specializing in anodize, chrome, and nickel plating. I could probably answer a few questions.

regarding powdercoating, if you only want the recessed areas powdercoated then you are looking at quite a bit of masking per piece, which could get expensive for that type of part. The high-temp masking tape is a little more expensive than general masking tape, and the layout could mean 5-10 mins ish per piece just masking. at $60 an hour for labor that is $5-$10 a piece before you even get to powdercoating them.

I would offer them as-is, and let the buyer decide how to handle the recessed area. Some may want to color match to the car, some may want to polish everything but the recessed areas, some may want it black or with CF inserts. Let them do it

yes, I think selling the badge unfinished is a good idea, just because I want everyone to be able to make it look how THEY want it to look.

But for my personal badges I'm defiantly going to have them professionally finished.

Do you know if the heat from the powder coating will affect the anodize?

There would really be no reason I can think of to do both anodizing and powder coating. The benefits of anodizing a part (color, scratch resistance, strengthening, and protection from elements, including sunlight, rain, chemicals, etc) are pretty much rendered useless if a powder coating is applied on top of it.

Powder coating will provide all these benefits, with the exception of actually strengthening the aluminum alloy, and you will have more options of colors, and the colors will be more consistent.

Since the aluminum will not be in some sort of high abuse area, I actually think PC will be a better option for your particular application.

But to answer your question, anodize coatings, no matter how thick are still subject to cracking (known as crazing in the biz) under extreme temperatures because of the coefficient of expansion in aluminum (aluminum oxide is hard and brittle, the base metal is soft and malleable). So I would probably pick one or the other.

The reason I wanted to both anodize and powder coat is to achieve two tone coloring, black and silver, So I was planing on anodizing the whole part hard clear and having the recessed area powder coated black.

I have seen some parts anodized two different colors, but they didn't turn out so well. As far as powder coating in two colors, I'm not sure if that's possible, please advise.

powder coating in 2 colours is definitely possible. Talk to mike or look at some of his pictures, his nismo rims are powdercoated orange and black. maybe send him a pm or something because he is a powder coater and he usually lets members send stuff to him for coating so he would probably know best.

That design will require some intricate masking to powdercoat the center...I do powdercoating, and personally I wouldn't want to do that. Too time consuming, which will run the price up even more..
