Powdered Vapour Disposition

Is apparently, according to the "watchmakers watchmaker" industry expert on the vostok europe special on ideal world (QVC alike) right now, what PVD stands for

Powdered vapour?

I think we need a scientist for this one!

Yep, I'm also wondering if it's well mannered

Lol. I'd missed that bit!

Peripheral Vascular Disease

Lost in translation?

Physical Vapor Deposition - This actually covers a range of vacuum deposition methods, some of which, may involve using powder as the material source. Basically you get the coating source hot in a near vacuum so it evaporates then it will condense out over the target item.

Some of the methods:
Cathodic arc Deposition
Electron Beam PVD
Evaporative Deposition
Pulsed laser Deposition
Sputter Deposition

There is also Chemical Vapor Deposition (CVD) which results in a similar type coating, but uses chemical reactions to deposit the coating. (DLC is a CVD coating.)
