Black Nitride vs Titanium aluminum Nitride PVD

Recommended Posts

Nitride chemically changes the surface of the steel and case harden's it. The "black" will burnsih on corners, high spots, and rubbing surfaces but the protection is stll there. Everthing else is a coating that can wear or even chip (to greater or lesser extents) in some cases exposing unprotected metal.

dlc is not decorative.

its a hard coating, and is superior to black nitride in surface wear resistance

black nitride hardens the metal to a substantial depth and makes for pretty good wear resistance, and really good long term wear.,

I prefer black nitride, with the understanding that my gun will have some visible long term wear marks, like a well used glock slide.

DLC is decorative.

Absolutely not true... DLC is a PVD applied impregnation of the metal... It is the process they use on high speed drill bits, and the cutting edge of tunnel Boring machines... Particle vapor deposition is the strongest, and most lubricious, route you can take for anything that's metal.
