Monitoring parameters for Plasma Spray

Hi Becky
Monitoring voltage alone with no reference to other parameter settings would probably be a waste of time. Assuming you are monitoring a spray system where all settable parameters are kept constant (you spray same coating all the time) then monitoring voltage over time for any individual nozzle/electrode hardware set-up would be useful. It is important that you are able to relate voltage with the other parameter settings particularly plasma gas flows, current, etc. and hardware.
An interesting point is that a few set voltage to a specific point and keep this constant, so that they always maintain a constant power output. In this case plasma gas make-up and flow become the variable.
Hope this helps.
Regards Gordon
