We have discussed similar approaches for a biprop engine. A copper inner
liner should be fine, assuming it's coated with a very adherent coating
within
the cooling passages, such as Nickel. Nickel *should* be nonreactive enough
to work at moderate temperatures, but we haven't tried this yet. I don't
know
if Tin would be adherent enough for this purpose.
