I vaguely remember a thread containing information about this process last year but can be of no other help beyonds that. It certainly looks intriguing, hopefully someone in the know will chime in.

 

It appears to be a plasma vapor deposited coating. It looks to be in the same basic family as IonBond, namely a diamond-like carbon.

The unique Duralar ArmorLube™ coating provides a combination of dry lubrication and exceptional hardness to enhance the performance of a range of metal products and parts in firearms, automotive, oil & gas and other industries. The coating is created from a proprietary carbon-based formula, with the carbon providing a natural graphitic lubricity and an extremely low coefficient of friction — less than 0.08. ArmorLube coating is well suited for applications that require a clean, dry, permanent lubrication — without needing oils or greases, which can accumulate dirt and cause fouling.

A further unique advantage for firearms applications is the fact that ArmorLube can be simultaneously applied to both the inside and outside surfaces of metal parts. This coating is deposited by the Duralar™ Emperion™ deposition system using the company’s proprietary DualArmor™ process. This bathes metal parts in a dense plasma, so that all surfaces — interior, exterior and complex 3D shapes — are coated with high uniformity and at a very high rate, without the line-of-sight limitations of spray-type coatings. The high deposition speed also allows ArmorLube coatings to be very thick — up to 15µm, if desired.

 

$450 for a handgun, plus shipping both ways. Yikes.
