Aftermarket metal coating with serious strength - suggestions?

[armoredman]

I am very fond of my SP-01 Phantom, fantastic sidearm, carry it often, but it has one, tiny, weak point - the mag release button rusts at the drop of a hat. I am almost daily scrubbing it and oiling it when I carry it, especially in AZ summer weather. I think the finish finally wore through last year with all the use I give it. What would a good coating I could afford do to stop this, any ideas? I've never used cold blue, don't know how tough that would be.

Depends on the material used for the part and how it was manufactured.

I'm a huge fan of salt bath nitrocarburization, also known by different names such as the proprietary Melonite, Tuftride, Tenifer and "QPQ".

This is a surface conversion process and not a coating and it's highly corrosion and wear resistant.

I am assuming the part is an MIM part which while designed to be manufactured by that process is porous and lacks the density of a CNC machined part.

Having something like Tungsten Diamond Like Carbon applied to a NEW part would be sufficient. 

After the part is media blasted and surgically cleaned it will have 5 to 7 microns of electroless Ni applied. Then it would have 3 microns of W DLC applied.

Ionbond does the latter. You may have to search to see who does the former with small parts.

You could also search for a non- MIM new part that is CNC'd and already coated. I haven't looked but CZ custom or Cajun might have one.

Cerakote and Dura cote can be applied at home but it seems a big hassle just to do a mag release. How about contacting Dan Wesson and see if they can apply their Duty Coat for you? That finish is pretty tough and gets good reviews.

CZC is right up the road from me....

Why not go for NP3?

Nitrided would probably be the best option

As for coatings, the more phosphorous the better the corrosion resistance, at least 9% for "high" resistance

Parkerizing
Standard phosphate coating for iron and steel

Nickel-Phosphorus
Uses nickel instead of manganese, increasing durability, can be applied to aluminum, titanium, iconel
Best option for corrosion resistance on low wear parts

Nickel-P-Boron
Adds boron nitride for increased lubricity and durability

Nickel-P-Teflon (NP3)
Uses Teflon instead of boron nitride

Nickel-Boron
Nickel and boron alloy, creates boron carbide where it meets the carbon in steel
Higher operational temps than NP3
Generally silver but can be made matte black

Nickel-Boron-Boron
Adds boron nitride for even better lubricity with the same high temp performance

A-man, I know you've had that pistol for quite some time, so it took a while to get to this point.  Is a possible solution just buying a new part from CZ to get another 5-6 years out of?  Today's parts might even have a more sweat-resistant coating.

I don't know. My 85C mag release lost its black color in about 1 month, and I didn't carry the 85C! That said, my S2 mag release seems to be doing better, but I think my hand just doesn't make as much contact.
