Metco 15F by Plasma F4
Hello, does anyone have a reference parameters for Metco 15F (NiCrFeSiBC) -50/23 for plasma (F4 gun)? I have a little problem with turbulence of powder (high roughness) using my developed parameters. Regards

Hi Anne
You could try with the parameters as bellow, I used this parameters with the powder FST M-771A.93 with excellent result, keep in mind that this material was designed in order to be fused after spraying and must be sprayed without bond coat, if you prefer to obtain a semifused coating is necessary to apply a NiAl bond coat

Gun - F4MB
Iniettor - Std, 1,5mm
Angle 90°
Iniettor distance - 6mm
Ar - 58
H2 - 12
Voltage about - 64 V
Carrier gas 3,6 -
powder feeder insert - NL/NL
Powder feed rate - 125 Gr/minute
Digital setting - 46
Stirrer speed - 60
D.E. could be about 76%
Best regards
Luigi
