Diamalloy 2004 surface roughness problem
Greetings to All,

I got a question here, I am using the Diamalloy 2004 powder for my HVOF coating and there is a problem on surface roughness. I am looking for 2.0mRa and below, but getting alomost double of the requirement. Anyone have any idea??
Thanks

Hi Khairul Anwar

Assume you mean 2 μm Ra for as-sprayed coating.

I would expect around 4 - 6 μm Ra for as-sprayed Diamalloy 2004. I doubt whether you could ever get it to spray finer than 2, in fact I think you would have problems getting any powder to spray finer than 2.
