Amdry 962 sprayed on labyrinth by F4 gun
Hi All,

Does anyone have the experience about Amdry 962 sprayed on labyrinth by F4 gun?

Now what I'm facing is the flection of the powder, which leads to lots of unmelted particles and high porosity in coating. The parameters are Current 650A Argon 40NLPM H2 12NLPM 150mm 40g/min.

Sorry I can't help you much more than to suggest that you also tell us what nozzle and injector you are using.

What is the carrier gas flowrate for powder?
Increase in primary gas flowrate may help you.
