Download or read book Production Problems Associated with Coating Refractory metal Hardware for Aerospace Vehicles written by W. A. Gibeaut and published by . This book was released on 1963 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four coating processes have been scaled up to coat components of aerospace vehicles: (1) slurry, (2) atmospheric-pressure pack cementa tion, (3) vacuum pack cementation, and (4) fluidized bed. The principal advantage of the slurry process is its ability to coat limited access areas such as the interior channels of built-up corrugated panels. This makes the process ideal for coating spot-welded corrugated panels after they have been welded. The other three coating processes, which are vapor-deposi tion processes, are not so suitable for coating limited-access areas. When they are used for parts such as built-up corrugated panels, the individual parts (including rivets) are coated, then riveted together, and then the entire assembly is recoated. This shortcoming is off set by the fact that the coatings applied by the vapor-deposition processes are more protective at higher temperatures than are the slurry coatings.

Available in PDF, EPUB and Kindle. Book excerpt: This memorandum summarizes information on refractory materials and composites as presented at the Eighth Meeting of the Refractory Composites Working Group in Fort Worth, Texas, January 14-16, 1964. This memorandum is based on 45 papers covering a wide variety of subjects ranging from basic studies on oxidation mechanisms to the development of specific pieces of hardware. The papers are reviewed and discussed briefly within the framework of the following four broad areas: materials technology, process technology, specific hardware applications, and evaluation techniques. Included in the section on materials technology are discussions dealing with bulk refractory materials and coatedmetal systems. Hot spraying, chemical vapor deposition, powder processes, joining, and extrusion are discussed in the section on process technology. The specific hardware applications cover rocket-motor components, nose caps, leading edges, hot skins, and fasteners. (Author).

Download or read book The Problem of Hydrogen in Steel written by A. R. Elsea and published by . This book was released on 1963 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum introduces the problem of delayed, brittle failures associated with hydrogen in steel, particularly high-strength steel. It is intended to help the steel user determine if he has such a problem. The effects of hydrogen on the mechanical properties of steel are dealt with, and the behavior of material susceptible to delayed, brittle failure is described. Also, the effects of such factors as strength level, magnitude of applied stress, hydrogen content, steel composition, test temperature, and strain rate on hydrogen embrittlement and the susceptibility to hydrogen-induced, delayed, brittle failure are discussed. Possible sources of hydrogen in steel and the types of tests useful in determining the susceptibility to delayed failure are outlined. (Author).
Download or read book Compatibility of Materials with Rocket Propellants and Oxidizers written by Walter K. Boyd and published by . This book was released on 1965 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The memorandum summarizes the available information on the compatibility of liquid rocket propellants with prominent materials of construction. Fuels and oxidizers of current interest are discussed. The corrosion data which are presented will apply to storing, handling, and control equipment outside of missiles and to missile components excluding combustion chamber. The compatibility of materials with reaction products in combustion chambers, nozzles, etc., is not considered. Included in the summary are data for many nonmetallic materials. The memorandum is subdivided into sections according to the propellant. Each material of construction is rated for a given medium as belonging to one of four classes, based primarily upon corrosion resistance. Consideration also is given to such factors as catalytic decomposition and sensitivity to impact.

Available in PDF, EPUB and Kindle. Book excerpt: A review of machining damage effects in beryllium was made. Surface damage is caused by twinning and microcracking as a result of various machining operations. Twinning is a result of surface working while microcracks initiate at intersections of twins and grain boundaries, at twin-matrix interfaces, at impurity particles, and in heavily twinned regions. These phenomena may be due to residual stresses in wrought products as well as machining parameters such as tool type, feed, and speed and depth of cut. The loss of mechanical properties due to machining damage is reviewed. Also presented is a study of surface damage actually encountered with machining of the shingles for the Gemini spacecraft.
