APS - Diamond film
I have to cover a metallic substrate with a diamond film .
The coating will be done with APS (Metco 7M with F4 gun or 7MB gun)
Is there anybody who could help me with any kind of informations ?

Thanks,
Ion

Hi Ion

You will not be able to apply diamond like carbon films using conventional atmospheric plasma spray. I suppose that these guns could be used as part of a PACVD (plasma assisted chemical vapour deposition) process with some serious modification. See Exnnerspray link and I think you will get the idea. Smile

I have plasma sprayed nickel/diamond coatings before, but I don't think this is what you are after.

Hello Mr. Gordon,

Thank you !
I know this process of diamant film deposition with a convential spraying equipment with vacuum plasma.
I read this article:
F. Deuerler, M. Pies, H. Van den Berg, R. Tabersky, V. Buck: Production, characterization, and wear behaviour of plasma jet CVD diamond films on hard metal cutting tools, phys. stat. sol. (a) 154 (1996) 403-422

And this:
C. A. Wolden, Z. Sitar, R. F. Davis: Combustion flame deposition of diamond, in: B. Dischler, C. Wild (eds.) Low-Pressure Synthetic Diamond, Springer Series in Materials Processing, Springer-Verlag, Berlin, 1998, p.41-58


But I do not have a vacuum cabin for plasma spraying and that is why I will try to obtain the diamant film with an APS equipment.I was wondering if someone with more experience than me, can give me some suggestions.

Kind regards,
Ion

Hi Ion

I think APS just will not work, you will need spray inside a chamber controlled environment, otherwise you will just be adding to global warming with CO2 Happy0193 rather than producing DLC films.

Hi,
Oxyacetylene flame at atmospheric pressure has been used for forming thin film of diamond on prepared substrate.I have given details of the process plus references in the chapter on 'Combustion Processes' of my book entitled as ''Advanced Thermally assisted Surface engineering Processes,Kluwer Academic Publications,2004,now taken over by Springer,NY.
