Available in PDF, EPUB and Kindle. Book excerpt: Codeposited coatings of pyrolytic graphite/silicon carbide were fabricated by chemical vapor deposition at temperatures ranging from 3000 F to 3800 F using methane and methyltrichlorosilane as precursors and nitrogen as a diluent and carrier. The effect of temperature and methyltrichlorosilane concentration on coating composition (SiC content) and morphology were determined. Specimens of codeposited coatings were fabricated to determine the physical properties, thermal stress state and erosion characteristics of various PG/SiC compositions. Coating samples were examined and characterized microscopically, by X-ray diffraction and by electron microprobe. (Author).

Book Synopsis Development of Pyrolytic Graphite/Silicon Carbide Composite Materials for Rocket-Nozzle Applications. Volume III. Comparison of Deposition Furnaces and a Generic Process Control System Specification by : G. E. Cort
Download or read book Development of Pyrolytic Graphite/Silicon Carbide Composite Materials for Rocket-Nozzle Applications. Volume III. Comparison of Deposition Furnaces and a Generic Process Control System Specification written by G. E. Cort and published by . This book was released on 1978 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final volume in a three volume set describing the pyrolytic graphite/silicon carbide (PG/SiC) coating development work at the Los Alamos Scientific Laboratory (LASL). In this volume we compare the injector deposition furnace with the channel flow furnace that was developed at LASL during this program. They are compared for ease of scaling to larger sizes and modeling with existing computer programs, and relative ease of implementing changes. A specification is given for a generic process control system for the PG/SiC deposition. A recommended step-by-step procedure to develop a coating furnace for a specified rocket-nozzle part is outlined and an example of its use is given. (Author).

Download or read book Development of Pyrolytic Graphite/Silicon Carbide Composite Materials for Rocket-Nozzle Applications. Volume II. The Channel Flow Deposition Furnace written by T. C. Wallace and published by . This book was released on 1978 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of instrumented engineering tests is described in which a 'channel flow' chemical vapor deposition furnace was used to prepare pyrolytic graphite/silicon carbide (PG/SiC) codeposited material for rocket-nozzle applications. The nozzle section and a water cooled center body formed a vertical annular flow passage for the coating gases. The nozzle section was inductively heated and was coated on the i.d. only. Well-mixed process gas entered the flow annulus with uniform velocity, temperature, and species concentrations from a plenum below the heated substrate. The flow could be either laminar or turbulent, but did not contain recirculating regions. An analytical model of the furnace and deposition process was developed to simulate the heat transfer in the solid components and the flow, chemical kinetics, and heat and mass transport associated with the process gas. Model predictions and test results on temperatures and PG/SiC deposition rates agreed very well. The coating microstructure and inferred quality were characterized by metallography and correlated with the process variables. The report includes detailed descriptions of the furnace, instrumentation, and test procedures in addition to plots of all reduced data. (Author).

Download or read book Development of Pyrolytic Graphite/Silicon Carbide Composite Materials for Rocket-Nozzle Applications. Volume I. The Injector Deposition Furnace written by T. C. Wallace and published by . This book was released on 1978 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of instrumented engineering tests with a chemical vapor deposition furnace used to prepare pyrographite/silicon carbide codeposited material for rocket nozzle applications is described. Flow into the furnace is an axisymmetric confined jet with high Reynolds and low Mach number. The gas flow within the furnace is characterized by a large separated flow region with associated hot spot and a high level of turbulence. Methods of instrumenting and collecting data, methods for defining the furnace and process characteristics, test procedures, recording and reducing data, data analysis, and model development are documented. Analytical models of the furnace during transient and steady state operation were developed and the results compared with the data obtained. Characterization of the coatings obtained and the associated deposition kinetics are also presented. (Author).
