This book was released on 1964 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a thin bumper target is impacted by a hypervelocity particle, a spray of particles is produced. Data are presented on the penetration of these spray particles into a witness plate for various bumper and witness plate materials, spacings, and bumper thicknesses. The exploding foil projection technique and associated diagnostics are also described.

Book excerpt: This paper presents experimental data and an computational model of the cold spray solid particle impact process. Copper particles impacting onto a polished stainless steel substrate are examined. The high velocity impact causes significant plastic deformation of both the particle and the sub- strate, but no melting is observed. The plastic deformation exposes clean surfaces that, under the high impact pressures, result in significant bond strengths between the particle and substrate. Experimental measurements of the splat and crater sizes compare well with the numerical calculations. It is shown that the crater depth is significant and increases with impact velocity. However, the splat diameter is much less sensitive to the impact velocity. It is also shown that the geometric lengths of the splat and crater scale linearly with the diameter of the impacting particle. It is hoped that the results presented will allow better understanding of the bonding process during cold spray.

Download or read book Cold Spray Technology written by Anatolii Papyrin and published by Elsevier. This book was released on 2006-10-04 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of this book is Cold Spray technology. Cold Spray is a process of applying coatings by exposing a metallic or dielectric substrate to a high velocity (300 to 1200 m/s) jet of small (1 to 50 μm) particles accelerated by a supersonic jet of compressed gas. This process is based on the selection of the combination of particle temperature, velocity, and size that allows spraying at the lowest temperature possible. In the Cold Spray process, powder particles are accelerated by the supersonic gas jet at a temperature that is always lower than the melting point of the material, resulting in coating formation from particles in the solid state. As a consequence, the deleterious effects of high-temperature oxidation, evaporation, melting, crystallization, residual stresses, gas release, and other common problems for traditional thermal spray methods are minimized or eliminated. This book is the first of its kind on the Cold Spray process. Cold Spray Technology covers a wide spectrum of various aspects of the Cold Spray technology, including gas-dynamics, physics of interaction of high-speed solid particles with a substrate as well as equipment, technologies, and applications. Cold Spray Technology includes the results of more than 20 years of original studies (1984-2005) conducted at the Institute of Theoretical and Applied Mechanics of the Siberian Division of the Russian Academy of Science, as well as the results of studies conducted at most of the research centres around the world. The authors' goal is threefold. The first goal is to explain basic principles and advantages of the Cold Spray process. The second goal is, to give practical information on technologies and equipment. The third goal is to present the current state of research and development in this field over the world. The book provides coverage and data that will be of interest for users of Cold Spray technology as well as for other coating experts. At the present time the Cold Spray method is recognized by world leading scientists and specialists. A wide spectrum of research is being conducted at many research centres and companies in many countries. New approach to spray coatings Results are exceptionally pure coatings Low spray temperature without degradation of powder and substrate materials High productivity, high deposition efficiency High operational safety because of absence of high temperature gas jets, radiation and explosive gases Excellent thermal and electrical conductivity Wide spectrum of applications because of important advantages of the process

Available in PDF, EPUB and Kindle. Book excerpt: High-Velocity Impact Phenomena covers a wide range of pertinent topics dealing with impact phenomena. The book discusses hypervelocity accelerators; stress wave propagation in solids; and the theory of impact. The text also describes the application of the theory of impact on thin targets and shields and correlation with experiment; the numerical evaluation of hypervelocity impact phenomena; and analytical studies of impact-generated shock propagation. The equation of state of solids from shock wave studies; metallurgical observations and energy partitioning; and engineering considerations in hypervelocity impact are also encompassed. Design engineers will find the book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: The Lunar Surface Layer: Materials and Characteristics focuses on the characteristics, nature, and materials located in the lunar surface layer, including lunar soil mechanics, water vapor adsorption, and soil behavior. The selection first elaborates on soil mechanics considerations in the testing of lunar soil models, an experimental study in lunar soil mechanics, and gravity effects on soil behavior. Discussions focus on cohesion in lunar soils, gravity effect on dynamic shear strength of soils, porosity, soil bearing strength, lunar effects, soil cohesion in the lunar environment, gradation, structure and contact characteristics, and statics and dynamics. The book then examines the investigation of soil adhesion under high vacuum; water vapor adsorption behavior of kaolinite after high-vacuum storage; and sonic velocity and shear strength of possible lunar surface materials. Concerns cover shear strength, sonic velocity, experimental apparatus, and calibration. The manuscript takes a look at the consideration of properties of simulated lunar soil with possible stabilization techniques; feasibility of remote compositional mapping of the lunar surface; thermal emission characteristics of mineral dusts; and thermal properties of postulated lunar surface materials. The selection is highly recommended for researchers wanting to study the lunar surface layer.
