Help settle an argument...parkerizing

[Noban]

My friend is thinking of refinishing his Colt 1911 and mentioned parkerizing. I told him (not that it matters) that parkerizing is a form of controlled rust, just like bluing. He argues it is a coating. Who wins the cigar?

 

[WIL TERRY]

He does; it's a coating for sure.

I know that blueing is "rustiing", but I've never heard it ascribed to phosphating(parkerizing).

bluing is "controled rusting". Parker is a chemicaly bonded coating.

 

[Cheapo]

Coating.

It's a Phosphate thing. One metal-phosphate is black (magnesium???), another is sage green.

That's the difference between "WWII" Parkerizing and Vietnam "M16" Parkerizing.

At one time, the "high tech" military finish was Parkerizing topped with a nice hard epoxy paint. Exterior rub-off and loss of protection took a lot longer to happen with that.

Then came NITRIDE finishes...topped with Parkerizing by a certain Austrian firm, if my sources are correct.

Looks like I'm buying the smokes.

Thanks all!

The phosphate finish that we refer to as Parkerizing(tm) was developed by the Parker Company. To be true Parkerizine(tm) the finish has to be applied either by the Parker Company or by their process, all other phosphate finishes are, therefore, not Parkerizing(tm). Phosphate finishs can come in several different colors depending on the metalic salts used.

The name was a copyrighted trade name but due to usage has slipped into the same situation as asprin (which was a trade name), Kleenex, Xerox (to some degree except the Xerox people will sue your pants off if you were to use their name to promote your copier) and a couple others.
