Processwise parkerizing and hot bluing are the same process.
The chemistry is different in that parkerizing is done in a solution of phosphoric acid and zink that may also contain some magnesium. Generally the color will be acheived by adjusting the solution to the steel.
It definitely is NOT a rustproofing just as bluing is not a rustproofing.
