Yes, Melonite/Tenifer/Tuftride/ QPQ are all variations of the ferric nitrocarburization surface conversion process. It's exceedingly wear and corrosion resistant.

Glock, Walther, H&K and polymer framed CZ pistols use this process. There may be others.

Then some form of polymer coating is applied - except for Glock which now uses a PVD (physical vapor deposition) coating on top.

This HK variant also used a PVD coating.
No polymer top coat could remotely be called "Hostile Environment" as it wears very easily.

PVD Coatings on the other hand can be Extremely Wear/Scratch resistant. I use End Mills with AlTin PVD coating to increase tool life 300-400%. The Color is kind of a Dark Purple/Dark Bronze. I have been pondering sending one of my frames out for coating

Just for reference, this is my G19.5 after 1,000 rounds. Not sure this new DLC coating Glock’s using is preventing a fair bit of cosmetic wear. Shoots fine though.

My VP9 looked much much better even after 7,000+.

Long as it runs and doesn't rust it's just cosmetic wear. Gives the gun character.
