You can have the spokes polished and black-chromed . However.
chromeplating covers cracks and may even cause them, which is why
stressed parts should not be chrome-plated.

The same applies to ion-plating, which is good for a matte result.

Or you can dip the spokes in hot oil and then bake it on in an oven. I
don't know if a microwave will do the the job.

Is there any sort of oxide treatment that might be suitable?
