STUDY OF DIFFUSION BONDING OF TUNGSTEN ALLOYS
Abstract
The development of methods of diffusion-bonding W sheets to withstand the high temperatures enc untered in rocket nozzles was continued. A literat re survey was made on brazing, diffusion in metals, diffusion bonding, and particularly increased joint remelt te perature by solid-state iffusion. Brazing fundamentals were studied to determine the effects of joint gap thickness and quality on ultimate remelt temperatuure. Remelt testing procedures were developed and the remelt temperatures data were reported for a Cu-brazed W sheet; a brazed and diffusion treated W sheet-Coast metals 62 Braze alloy, under different loading, and brazed and diffusion treated in a vacuum; and an as-brazed W sheet. etallographic studies were made of as-brazed and brazed-plus-diffusion-treated coast metals 62 joints. The nozzle is being designed. Rocket motor cases have been obtained and solid propellant grain configuration i being designed.
