thermal spray metco 204ns coating
Is there somebody who can help me with a perameter to spray 10% to 20% porosity on a more repeatable perameter. I have 3m/7m/9m/sg100 . My customer uses amperit#828 aggl,sint but my boss wants me to develope 204ns this is spherical powder and it's not going to well . also will slower S/F per min give higher %. any way Im under a time deadline and the wife is not a big fan of the late nights at the booth., thanks for any help retlaw

Hi retlaw

Sign0016 to the Surface Engineering Forum.

A few questions to get the ball rolling:

What parameters are you using?

What typical level of porosity are you getting? Is it denser than you want?

When you say "more repeatable" does that imply that results for a certain parameter set give you inconsistent results?

Are you confident that your metallographic analysis of porosity is true or consistently accurate?
