Metco 308NS Abradable

[KevGarty]

Hello everyone.

Has anybody ever successfully sprayed Metco 308NS with Plasma? Im struggling to find parameters (even from Metco)

We currently use Flame but use Plasma for everything else. Looking to consolidate everything to Plasma spray to reduce change over times

Any assistance would be greatly appreciated

All the best

Hi Kev
Yes of course you can spray with Aps, at low amps, I used to spray it with F4 gun, but depend of the specification you need to reach.
