Journal ArticleDOI
Bonding mechanism in cold gas spraying
TL;DR: In this paper, a hypothesis for the bonding of particles in cold gas spraying, by making use of numerical modelling of the deformation during particle impact, is presented, with the results of modelling assessed with respect to the experimentally evaluated critical velocities, impact morphologies and strengths of coatings.
Journal ArticleDOI
Development of a generalized parameter window for cold spray deposition
TL;DR: In this article, the influence of impact conditions and related phenomena on the coating quality was investigated through spray experiments, which were complemented by ballistic impact tests and explosive powder compaction.
Journal ArticleDOI
Cold spraying - A materials perspective
TL;DR: In this article, the authors provide an overview of the cold spray process, the current understanding of the deposition mechanisms, and the related models and experiments, from a materials science perspective.
Journal ArticleDOI
From Particle Acceleration to Impact and Bonding in Cold Spraying
Tobias Schmidt,Hamid Assadi,Hamid Assadi,Frank Gärtner,H.J. Richter,H.J. Richter,Thorsten Stoltenhoff,Heinrich Kreye,Thomas Klassen +8 more
TL;DR: In this article, the authors summarized the state of the art in these theoretical studies, alongside a comprehensive description of the process, and also discussed the prediction of coating properties in the light of modeling combined with experimental investigations.
Journal ArticleDOI

Hamid Assadi,Hamid Assadi,Tobias Schmidt,H.J. Richter,H.J. Richter,Jan-Oliver Kliemann,K. Binder,Frank Gärtner,Thomas Klassen,Heinrich Kreye,Heinrich Kreye,Heinrich Kreye +11 more
TL;DR: In this article, a method for the construction of the window of deposition and the selection of optimum process parameters is presented for cold spraying, where particle impact velocity and the critical particle velocity for bonding are worked out and expressed explicitly in terms of key process and material parameters.
