300C ROTATING RECTIFIER ALTERNATOR, PHASE I-B.

Abstract

The various parameters controlling the growth of grown junction crystals are under control. Diodes were fabricated from recent growth runs which meet specifications. A feasibility study of high temperature nitrogen diffusion is under way; no usable diodes have been prepared as yet. Some success was achieved in gold plating the tungsten disc. Tungsten discs thus protected could operate in air at elevated temperatures without degradation. A number of diodes were tested to 500C (one diode to 600C) in argon. A new electrical test unit was used which closely simulates rectifier operation in an alternator. Exposure tests of the 'statorette' in polyphenyl ether atmosphere at altitude has been completed. Preliminary electrical results appear promising, however, physical appearance revealed some degradation of portions of the conductor insulation. (Author)
