| Abstract: |
Locally Fluidized Thermal Spray Powder Feeders have been commercially available for the past 25 years and have fundamentally different operating characteristics than the classic Volumetric Powder Feeder. This paper explores the design principles and factors effecting the operation and performance of this technology. The discussion will include the challenges faced in accurately and safely metering powder into high backpressure spray torches.
