@MusbJim has the answer. Chrome can be removed through a chemical process. It can probably get pricey but powder coating won’t stick to a chrome surface. Bead blasting or sand blasting or any other abrasive removal of the chrome will cause more trouble than it’s worth in the long run because of the damage that will happen to the metal underneath.
As far as applying chrome or power coating he is right again. I highly recommend you gather up ALL the stuff you want coated and get it done in one batch. You’ll get over the initial shock of the cost for everything being done at once as it will almost certainly be lower than a total if you made multiple jobs out of it.
