@sprayloud, thanks for your reply.
I want to both study the theory and practically operate the equipment (not always though).
I have read many many articles and papers and I already have basic understanding of coating and hyper-sonic thermal spray.
But to get a more complete knowledge, I think I'd better turn to books than just read articles.
You indeed gave me an idea, I will look into thermodynamics.

Thanks!

It might be a weird question posted here but I still want to get your opinions 
What knowledge should one acquire if one is determined to work on HVOF/HVAF thermal spraying.
PEACE 
What do you mean by "work on HVOF/HVAF thermal spraying" ?
Actually spraying and working everyday with equipment or studying coating formation processes, thermodynamics and so on.
A good place to start for theoretical knowledge would be articles from, for example, sciencedirect.com
