This book was released on 1970 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: AN INVESTIGATION WAS CONDUCTED TO DETERMINE THE INFLUENCE OF A SULFUR-CONTAINING GAS ON THE ADHESION OF IRON (011) SURFACES. EXPERIMENTS WERE ALSO DONE WITH EQUIVALENT SURFACE COVERAGES OF SULFUR, OXYGEN, AND THE SULFUR-CONTAINING GAS HYDROGEN SULFIDE TO DETERMINE WHICH HAD THE GREATEST INFLUENCE ON ADHESION. THE STUDIES WERE MADE IN A VACUUM APPARATUS CONTAINING BOTH LEED AND AN AUGER SPECTROMETER TO DETERMINE THE PRESENCE AND ARRANGEMENT OF SULFUR, OXYGEN, AND HYDROGEN SULFIDE ON THE IRON SURFACE BEFORE AND AFTER ADHESIVE CONTACT. A 3.00-MM-DIAMETER FLAT CONTACTED A LARGER (8.0-MM DIAM) IRON (011) SURFACE UNDER APPLIED FORCES OF FROM 20 TO 350 DYNES (2 X 10( -4) TO 3.5 X 10( -3) N). ALL ADHESION EXPERIMENTS WERE CONDUCTED AT 10( -10) TO 10( -11) TORR. THE RESULTS OF THE INVESTIGATION INDICATED THAT ADSORBED SULFUR AND HYDROGEN SULFIDE EXERT A STRONGER INFLUENCE ON THE ADHESION OF ONE IRON SURFACE TO ANOTHER THAN DOES OXYGEN. AT A GIVEN APPLIED FORCE, INCREASING SURFACE COVERAGE WITH HYDROGEN SULFIDE REDUCED THE ADHESIVE FORCE. AN AUGER ANALYSIS REVEALED THAT SULFUR CAUSES GREATER DIFFICULTY IN OBTAINING AND MAINTAINING A CLEAN IRON SURFACE THAN DOES CARBON.

This book was released on 1973 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of sulfur and oxygen with an iron surface was studied with Auger spectroscopy analysis both statically and during sliding-friction experiments in a vacuum environment. Oxygen, hydrogen sulfide, methyl mercaptan, and sulfur dioxide were adsorbed to an iron surface. Results indicate that sulfide films formed on clean iron surfaces are completely displaced by oxygen. Hydrocarbons containing sulfur, such as methyl mercaptan, adsorb dissociatively. Less sulfur is adsorbed during sliding with hydrogen sulfide and methyl mercaptan than in the absence of sliding. With both oxygen and sulfur dioxide, sliding did not affect the amount of material adsorbed to iron.

Download or read book Auger Electron Spectroscopy written by Donald T. Hawkins and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: Auger electron spectroscopy is rapidly developing into the single most powerful analytical technique in basic and applied science.for investigating the chemical and structural properties of solids. Its ex plosive growth beginning in 1967 was triggered by the development of Auger analyzers capable of de tecting one atom layer of material in a fraction of a second. Continued growth was guaranteed firstly by the commercial availability of apparatus which combined the capabilities of scanning electron mi croscopy and ion-mill depth profiling with Auger analysis, and secondly by the increasing need to know the atomistics of many processes in fundamental research and engineering applications. The expanding use of Auger analysis was accompanied by an increase in the number of publications dealing with it. Because of the developing nature of Auger spectroscopy, the articles have appeared in many different sources covering diverse disciplines, so that it is extremely difficult to discover just what has or has not been subjected to Auger analysis. In this situation, a comprehensive bibliography is obviou-sly useful to those both inside and outside the field. For those in the field, this bibliography should be a wonderful time saver for locating certain references, in researching a particular topic, or when considering various aspects of instrumentation or data analysis. This bibliography not only provides the most complete listing of references pertinent to surface Auger analysis available today, but it is also a basis for extrapolating from past trends to future expectations.

This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of new materials is recognized as one of the major elements in the overall technological evolution that must go on in order to sustain and even improve the quality of life for citizens of all nations. There are many components to this development, but one is to achieve a better understanding of the properties of materials using the most sophisticated scientific tools that are available. As condensed matter physicists and materials scientists work toward this goal, they find that it is useful to divide their efforts and focus on specific areas, because certain analytical and theoretical techniques will be more useful for the study of one class of materials than another. One such area is the study of metals and metallic alloys, which are used in the manufacture of products as diverse as automobiles and space stations. Progress in this area has been very rapid in recent years, and the new developments come from many different countries. For these reasons the Advanced Research Workshop Programme in the NATO Scientific Affairs Division has seen fit to sponsor several meetings to bring together the researchers and students working in this field from the NATO countries and elsewhere. There have been a series of NATO-ASI's that have dealt with the results of research on the electronic structure of materials and the properties of metals, alloys, and interfaces. They are: "Electrons in finite and infinite structures" P. Phariseau and L.

This book was released on 1970 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three displays were evaluated on a piloted simulator, each of which provided information which could be used in thrust management. The three displays were (1) rate of change of speed, (2) potential flight-path angle, and (3) potential rate of climb. Results are presented in the form of time histories, histograms, and pilot comments. The results include comparisons of flight-path and speed control and throttle activity with and without each display and pilot comments.
