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

This book combines the contributions of experts in the field to describe the behavior of various materials, micromechanisms involved during processing, and the optimization of cold-spray technology. It spans production, characterization, and applications including wear resistance, fatigue, life improvement, thermal barriers, crack repair, and biological applications. Cold spray is an innovative coating technology based on the kinetic energy gained by particles sprayed at very high pressures. While the technique was developed in the 1990s, industrial and scientific interest in this technology has grown vastly in the last ten years. Recently, many interesting applications have been associated with cold-sprayed coatings, including wear resistance, fatigue life improvement, thermal barriers, biological applications, and crack repair. However, many fundamental aspects require clarification and description.

This book first presents different approaches to modeling of the cold spray process with the aim of extending current understanding of its fundamental principles and then describes emerging applications of cold spray. In the coverage of modeling, careful attention is devoted to the assessment of critical and erosion velocities. In order to reveal the phenomenological characteristics of interface bonding, severe, localized plastic deformation and material jet formation are studied. Detailed consideration is also given to the effect of macroscopic defects such as interparticle boundaries and subsequent splat boundary cracking on the mechanical behavior of cold spray coatings. The discussion of applications focuses in particular on the repair of damaged parts and additive manufacturing in various disciplines from aerospace to biomedical engineering. Key aspects include a systematic study of defect shape and the ability of cold spray to fill the defect, examination of the fatigue behavior of coatings for structural applications, and a novel working window at subcritical conditions to obtain porous structures. This book is exceptional in scope, and its review of finite element modelling at different length scales sheds light on future design and process improvement in emerging applications such as structural repair, metal additive manufacturing and metal foam design.

The cold spray deposition process involves the acceleration of solid particles to high velocity by a carrier gas which is often supersonic, and the subsequent impingement of this high velocity, particle laden jet onto a substrate. In order for deposition to occur, i.e. in order for the solid particles to bond to the substrate, the impact velocity of the particles must be equal to or greater than some critical value. To determine an estimate of this critical velocity, the energy principle was used to predict a critical impact velocity based on material properties. It has been shown that during its interaction with the substrate, a particle should reach around 70% of its melting temperature to obtain good mechanical bonding. Using computational fluid dynamic models (CFD), a novel Aerodynamic Focusing Nozzle (AFN) using helium as the carrier gas, was developed and experimentally tested. The CFD models showed that a lighter gas such a helium must be used for the nanoparticles to reach critical velocity and penetrate the normal shockwave upstream of the substrate with sufficient inertia. A prototype AFN nozzle was fabricated using a rapid prototype machine and used to cold spray 300 nm diameter particles onto both aluminum and Kapton substrates at room temperature. Additional validation of the feasibility of the design was obtained through the deposition of a thin conductive copper layer of Kapton. This research focuses on the numerical modeling, as well as the construction and experimentation required for the development of the AFN for cold spraying nanoparticles. To characterize the results in a general way, a non-dimensionalization of all the factors involved was conducted and validated to determine the combination of cold spray process parameters required for the particle to reach the critical impact velocity and temperature.
