Manufacturing Methods and Technology Measure for Microwave Ferrite Powders for Arc Plasma Spraying.

Abstract

Commercially available spray-dried lithium powders were selected for the arc plasma fabrication of C-Band and S-Band phase shifters. Several spray-dried powders were evaluated and only those which flowed freely were suitable for the arc plasma spray (APS) process. Selected spray-dried powders were sprayed over a range of arc plasma conditions and the magnetic properties measured to determine the best APS parameters for fabricating phase shifters. The necessary ovens and control equipment were designed and built for spraying phase shifters. Several different dielectric compostions which were to be used as inserts for phase shifters were evaluated. Non-reciprocal. Waveguide, ferrite phase shifters were fabricated by arc plasma spraying, and the devices tested for insertion loss and differential phase shift. (Author)
