Plasma Gun Comparison

[Met.Eng.]

Hi,

we are planning to Plasma spray investing soon. We have many options but we were unstable betweenthe two options for gun. First one is F4 MB the other one is SG-100. We will do small and medium coating jobs. Generally we are planning to spray CrO and alloys and ZrO & alloys may be we will try to spray carbides , also we have 2 HVOF systems but i dont know anything about carbide spraying perfonmance with plasma. But generally we will spraying OxideCeramics with this system.

What do u think is there any qualty difference between these two guns? DE, Coating Densty, Coating adhesion strength? Does anyone have informations on this subject? I request ur help.

Thank you

Hi,

I do not have any experience with the SG 100, but I used the F4 as a booth operator years ago, and I liked it. It ran well, for long hours before rebuilding. I sprayed CrO, TBC's, carbides, SiAl polyester, YSZBn Polyester, just about anything. I found this thread here on this forum, have you seen it?

I had been waiting to see what Gordon, Luigi or Vadim might have to say, I respect their knowledge very much.

I too am also curious about actual experiences with the SG100 especially using with internal powder injection, what benefits it offers?

Internal powder injection makes the powder jet narrower and improves deposition efficiency. However, this effect is much greater with an axial powder injection in an Axial III burner.

Does anyone have knowledge on this subject???
