Oh, forgot to ask if the DLC coating requires secondary or even tertiary processing
(aka...machining)
CVD (Chemical Vapor Deposition) diamond is an old process and is a random locational
process. Meaning the laying down of diamond molecules is random and you can NOT
place them were you want. Most know it as synthetic diamond, but that
is a misnomer, as it is real diamond....just man made
Meaning that the finished product is in the 'general' shape of the anvil or target
surface, but has a rough surface that requires secondary and even tertiary processes
to finish it to what is desired
DLC (diamond like carbon) is new to me and am going to read up on it. This is
generally an Ion Beam or RF application and is NOT a polycrystalline (where as
CVD is). This makes it tougher and don't know, yet, if it is smooth in finish
like my old tungsten disulfide was (yet)
Since DLC is not in a crystalline structure, it is not brittle like CVD is
Am assuming it has the non-stick and slipperiness that CVD/diamond
has and is tougher. This is where it is getting very interesting to me
as it does require the pressures (at the deposition site) but is NOT
crystalline...almost an oxymoron to me...
CVD is in a much higher environment during deposition and my processes
is with RF at +1K*C. DLC is at a much lower temp environment...in
the <150*C range
This knowledge is so important for me to take the next step in helping diagnose
the failure mechanism(s) of this pump.
But that is mainly to stick with the architecture and form factor
of 'this pump'.
