Deposit Efficiency
Hello All,

Trying to get better deposit efficiency using Sg-100 with argon primary and nitrogen secondary. Parameters of 110 psi on Argon and 60 psi on Nitrogen,and 40 psi on carrier gas. Running at 650 amps around 46 volts.
The coating looks good and clean but DE is off around 15%. Standoff is at
4". Wondering if I've got to much velocity. Any suggestions would be appreciated. Joe

Hi Joe

I think we will need more info to comment. What powder are you spraying? and are you using a recommended parameter set for equipment and powder?

I'm unclear as to whether you mean you are getting 15% deposit efficiency which is very low or that you mean 15% deviation from an expected level.

If D.E. is around 15%, you are having a very poor efficiency, becouse ussually you can get from 60 to 90 %, depend of the powder and thermalspray equipment been used.
Best regards
