How about sand blasting?

I've read about chemical removal but it's expensive.

I ground the chrome off a bumper, primed it, sanded it and painted it with no problems. I also just recently sanded the chrome off with a DA and 180 grit paper on a hood trim piece. I also took care to wear a respirator when I did this, I didn't want to inhale any chrome dust.

I'd rather have chipped chrome and rust than dip a bumper or any other steel part of a car in hydrochloric (muriatic) acid.

You don't need to completely remove the chrome to powder coat over it. Is the chrome peeling and flaking off badly?

Another thing: Besides the weakening of the steel if you use acid to remove the chrome, that acid bath reverse electrolysis thing in that thread may produce serious toxins. Remember hexavalent chromium is "the stuff that made Erin Brockovich famous."

See, for example, Safety and Health Topics Hexavalent Chromium

That seems to me to be the most sensible approach. It's also got some support in a comment by Ted Mooney, P.E. at

Chrome metal is harmless, but when you electrolytically create toxic, carcinogenic, hexavalent chromium, well that's something else.
