Book excerpt: The report presents a detailed review of available information on the oxidation of W and its alloys. W is relatively inert below 700 C. As the temperature is increased above this level, however, oxidation becomes progressively more rapid, reaching catastrophic rates at temperatures around 1200 C and above. Various theories for the mechanism and rates of W oxidation at different temperatures are reviewed, and the effect of pressure and water vapor on the stability of W oxides is discussed in detail. The elevatedtemperature reactions of W with other materials, such as refractory oxides, and with gases other than oxygen also are covered. Information on the protection of W by alloying and coating is included. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Three coating systems were developed that protected 60 mil tungsten sheet from oxidation in air at elevated temperatures. These composites, applied by the vacuum pack process, were; silicon-tungsten; titanium zirconium silicon tungsten, and; titanium zirconium-boron silicon-tungsten. A laboratory scale process for application of each coating to tungsten sheet was developed and optimized. Oxidation characteristics of the coated systems in air under various static and cyclic conditions were determined from 1600° to 3650° F with several hours protection being achieved under cyclic conditions at 3550° F. Tensile tests were conducted on two of the three systems at regular temperature increments from room temperature to 3300° F under various environmental conditions. Stress oxidation, thermal shock, and hot gas erosion tests were also con ducted on the diffraction patterns were determined on the silicon-tungsten and titanium zirconium silicon-tungsten composites in the coated and exposed conditions.

This book was released on 1963 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidation at elevated temperatures of Zr-Th, Zr-Y, Hf-Y, Hf-W, Hf-W-Re, Al-Cr-Sn, and Al-LaSn alloys, as well as ZrN, HfN and ZrN-ThN combinations was studied in order to clarify specific aspects of the problem of protecting W against oxidation at high temperatures. Experimental results showed that there was much less tendency for ZrO2, ThO2 and HfO2 scales to crack during growth at high than at low temperatures. Multiphased scales were more resistanct to spalling than single-phased scales, and protective oxides were grown many alloys. However, even in sound and coherent scales composed of these oxides, O diffused so rapidly that it is doubtful that they could form the basis of a protective system at 2000 C. (Author).
