Selective leaching Wikipedia
Graphitic corrosion is selective leaching of iron, from grey cast iron, where iron is removed and graphite grains remain intact. Affected surfaces develop a layer of graphite, rust, and metallurgical impurities that may inhibit further leaching. The effect can be substantially reduced by alloying the cast iron

Selective leaching Wikipedia
Selective leaching, also called dealloying, demetalifiion, parting and selective corrosion, is a corrosion type in some solid solution alloys, when in suitable conditions a component of the alloys is preferentially leached from the material. The less noble metal is removed from the alloy by a microscopicscale galvanic corrosion mechanism. The most susceptible alloys are the ones containing

That is, iron metal is the reduced form of iron. The rust that is on it is it''s oxidized form because it has combined with oxygen to make iron oxide. If you take iron oxide and put some rust remover (reducing agent) on it you remove the oxygen and reduce the metal back to pure iron. Now, halides are not metals. In fact they are the opposite.
