Download or read book The Influence of Gaseous Environment on the Self adhesion of Metals written by William Gilbreath and published by . This book was released on 1968 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The self-adhesion of metal surfaces was measured in various gases with pressure, exposure duration, and temperature as variables. Aluminum, copper, gold, lead, magnesium, and titanium were studied in air, argon, carbon monoxide, ethylene, hydrogen, nitrogen, and oxygen. The results showed that loss of adhesion for a particular metal resulted from gas absorption on its contacting surface and that the effect of environment upon adhesion could be related to the heat of absorption for the particular metal-gas interaction.

Available in PDF, EPUB and Kindle. Book excerpt: Proceedings of the XXth International Astronautical Congress compiles selected papers presented at the 20th International Astronautical Congress held in Mar del Plata, Argentina in 1969. This book is divided into five main topics—spacecraft engineering, astrodynamics, astrionics, bioastronautics, and problems of education. In these topics, this compilation specifically discusses the equatorial vibrations of a long flexible boom on a spin-stabilized satellite of non-zero radius; heat transfer to linear bodies in two-dimensional hypersonic low density; and limits of accuracy of general perturbations for satellites moving under constant forces. The rapid optimization of multiple-burn rocket flights; data transmission for planetary studies; and comparison of theoretical and experimental attitude data for the DODGE spacecraft are also elaborated. This text also covers the Apollo life-support and protective systems; bioastronautical aspects of Apollo biomedical operations; and development and applications of hot water rockets. This publication is recommended for astrophysicists and scientists of other disciplines related to astronomy.

This book was released on 1967 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adhesion of metals is a complicated function of bulk and surface properties. Experiments, performed to define and evaluate the properties which influence the adhesive behavior of contacting bodies, showed that the interaction of the metal with its environment, the nature of any resulting contaminants formed on its surface, and certain mechanical properties (e.g., tensile strength, penetration hardness, and ductility) related to the plastic and elastic properties of the material were most important. To assess the influence of these properties, the adhesion of initially clean surfaces, generated by fracturing metals in an ultra-high vacuum, was monitored as a function of carefully controlled test parameters -- material, gaseous environment, exposure time, load, contact time or load duration, temperature, and vibration.
