Dwight, I too would like to postulate,
We have two different compounds here and neither is stable. There are two types of water compounds. H2O or regular water and H3O or heavy water. Heavy water is an instable compound that exists in minute quantities in reqular water. The H atom can be ripped from the weak H3O compound to form an acid with other impurities in the water and an unstable H2O. This unstable H2O then is free to search for another compound or atom to try to become a stable compound. Iron (FE) has a stronge affinity for the oxygen atom and will form an irreversible compound (FEO) or rust.
Hemoglobin or Haemoglobin (different spelling for the same thing) is the glue that holds the oxygen atom to the red blood cell (RBC) and also gives the RBC its color. But not all RBC's are coated with the same amount of Hemoglobin. So a metal such as iron (FE) can rip an atom of oxygen off of a RCB pretty easily to form rust.
In both instances we have a three way chemical reaction. There are the compounds involved to form the rust bluing in WW1 and the ones to form the salt bluing in WW2. In instance one, are the metals in rust bluing strong enough to rip the oxygen atom from H3O but weak enough to allow that atom to be ripped off to unite with iron to form rust? The same anology can be made regarding Haemoglobin. The second instance involves the analsis as to whether the chemicals involved in salt bluing will formulate the same reaction.
The final question, of course, would be which of these four reactions, while being ever mindful of solution impuities, will occur the quickest? Hell, I don't know!
