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.
