The corrosive ability of molten boron oxide is presented. A sequence of thirty environmental exposures of hightemperature alloys and ceramic coatings typical of those available for use in aircraft power plants was completed. The static exposure conditions consisted of the cyclic immersion of unstressed test materials in molten boron oxide at 1600 to 2100 deg F and in atmospheres consisting of air, air containing water vapor, or helium. The results indicate that the presence of aluminum as an alloy constituent or as a surface coating can cause catastrophic corrosion of that alloy at relatively low temperatures. (auth)
