question on some amperit powder

[Intel55]

Can you substitute 584.072 ( CrCNiCr 38/10) with 588.074 (CrCNiCr 45/15)? Using a DJ gun.

The 588 is for kerosene guns though. So does that mean the 588 is a finer powder carbide? The 584 is listed as a medium carbide. So I am thinking that the 588 might not work as well as a substitute.

any ideas?

thanks

also anyone ever heard of a "Gator Guard Gun?"

Hi Intel55

Amperit 588.074 is actually a slightly coarser powder than 584.072. I would guess that it may not produce the same quality of coating or deposit efficiency. The only sure way to find out is to test them side by side. Powder selection is critical if you want to get the very best coatings and deposit efficiency from your particular process. One powder may give excellent results through say a JP5000, but not quite so good through a DJ2700 or visa versa.

"Gator Guard Gun?" Gator-Gard is a proprietary plasma spray system license to Sermatech. Basically, it is a nozzle shroud/accelerator attachment, that aids high energy plasma spraying. The few coatings that I've seen from this system look very impressive, certainly when compared to standard plasma spray coatings.
