I've had several crankshafts surface hardened with a prosess called Nitriding. It hardens the journal surface a bunch.While it does not increase the overall strength of the piece, you can also have the crank shotpeened which helps overall. There is also a prosess called Tuftriding and this also hardens the journal surfaces. I've heard it's expensive though.
