I don't know myself, but I've asked a few people. The stock answer
seems to be "the droplets (splats) are so tiny that there is minimal
heat transfer" - in other words "magic". For more specifics, you
might try looking up Richard Knight of Drexel University; he's on the
web. He knows all about it and has been very helpful to me.
Even better, you could go to http://www.asm-intl.org/tss/list.htm ,
and get on the Thermal Spray Society mailing list, and ask the locals.
I know Dr. Knight posts there. It hasn't been very active lately,
they could use a question or two.
