Manufacturing Methods and Technology Measure for Arc Plasma Sprayed Phase Shifter Elements.
Abstract
Data on plasma spray conditions are discussed for seventy-one APS samples produced during this quarter. Spray deposition and sample transfer rates of one full length phase shifter every twelve minutes was obtained with a high velocity plasma gun assembly, but the samples showed cracks in the ferrite layer. We have established the source and corrected a major cause of this cracking by changing the anode geometry on the arc plasma gun. Microwave and hysteresis loop properties are reported on a number of APS prepared samples. Because of the cracking problem the saturation phase shift is low approximately 300 deg per full length sample; the insertion loss remains low less than 0.5 dB despite the presence of cracks.
