Journal ArticleDOI
Cold spray coating: review of material systems and future perspectives
TL;DR: In this article, cold gas dynamic spray or simply cold spray (CS) is a process in which solid powders are accelerated in a de Laval nozzle toward a substrate, and if the impact velocity exceeds a threshold value, particles endure plastic deformation and adhere to the surface.
Journal ArticleDOI
Experimental assessment and simulation of surface nanocrystallization by severe shot peening
S.M. Hassani-Gangaraj,S.M. Hassani-Gangaraj,Ki Sub Cho,Ki Sub Cho,Hyon-Jee Lee Voigt,Mario Guagliano,Christopher A. Schuh +6 more
TL;DR: In this paper, a model linking finite element simulation of severe shot peening to dislocation density evolution due to the accumulated plastic strain was developed to predict the resultant grain/cell size gradient in the surface layers.
Journal ArticleDOI
Critical review of corrosion protection by cold spray coatings
TL;DR: A critical review of cold spray for corrosion protection is presented in this paper, where the effects of deposition temperature/pressure, particle size, coating thickness, carrier gas, post-treatment, and co-deposition of metals and ceramic particles on corrosion behaviour are discussed.
Journal ArticleDOI
Fatigue behavior of cold spray coatings: The effect of conventional and severe shot peening as pre-/post-treatment
Atieh Moridi,Atieh Moridi,S.M. Hassani-Gangaraj,S.M. Hassani-Gangaraj,Simone Vezzù,Libor Trško,Mario Guagliano +6 more
TL;DR: In this paper, the fatigue behavior of Al 6082 cold spray coating with the same material as substrate is studied and the possibility of improving the load bearing capacity of the cold spray coated specimens by shot peening process is explored.
Journal ArticleDOI
Nitriding duration reduction without sacrificing mechanical characteristics and fatigue behavior: The beneficial effect of surface nano-crystallization by prior severe shot peening
S.M. Hassani-Gangaraj,S.M. Hassani-Gangaraj,Atieh Moridi,Atieh Moridi,Mario Guagliano,A. Ghidini +5 more
TL;DR: In this article, a combination of severe shot peening with nitriding at 7.5 h is assessed and it is affirmed that improvement by hybrid treatment can be actively exploited in the form of duration reduction.
