Hi Andrea,
concerning the 75° angle: is the flow direction "against" the flow direction of the plasma flame. If so, maybe try a 90° angle.
But the main problem could be the grain size
MetCO 45 VF-NS is a -45 + 5 µm : VF Very fine
I propose for atmospheric plasma spraying APS you should try the coarser type 45 C-NS.
Then 90°- injection angle and play a little with your secondary gas -> hydrogene or nitrogene, or with the electrical current.
If you want you can send some more information about your process - I might give you some more ideas.
Good luck and greetings from
Mannheim - Germany
