Cast Iron Parts can be restored using NI-Al wire very effectively.

flame spray metco 450 or 405 for wire
plasma metco 480 or 450 or many others.
wire arc tafa 75b
a few examples of NiAl 95/5

Thank you all for your helpfull replies:
What do you think about TAFA 95MXC wire with iron base for cast iron substrate.

[kschewe]

That wire is a iron chrome which can be applied to cast. You can use that coating and tafa states can be applied excess of .060 thick.
I think that is a good top coat and I would build up or bond with a NiAl (75b) first if you require a large deposit. Otherwise less then .015 I would just use the 95mxc. Make sure the cast is clean and sometimes you might have to bake it to get all the oils out of it.
