RE: HVOF: Gas fired system Vs liquid fired system
We have and use both types, we have a JP500, and a couple of MEC microjets. The microjets are far more effeciant for smaller areas, with vastly less heat input as well. They also have the advantage of being very close to maintainance free. The jp is still king for larger areas at the moment, although we do have plans that may change this.
Quite honestly if you are spraying thick coating on big areas, then i would go liquid fuel, if youre looking to do more intricate parts, then i would go with a smaller gas fuelled gun.
