Gas dynamic principles of cold spray

Journal of Thermal Spray Technology, 1998
This paper presents an analytical model of the cold-spray process. By assuming a one-dimensional isentropic flow and constant gas properties, analytical equations are solved to predict the spray particle velocities. The solutions demonstrate the interaction between the numerous geometric and material properties.

Effect of gas pressure on Al coatings by cold gas dynamic spray

Materials Letters, 2008
Al coatings by cold gas dynamic spray (CGDS, or Cold Spray) technique with pressure condition were investigated. The relatively soft Al has been coated at low gas pressure condition (0.7 MPa) with severe plastic deformation. However, the Al particles in the coatings coated at the higher pressure conditions (1.5 MPa, 2.5 MPa) were not severely deformed.

Study on Process Optimization of Cold Gas Spraying

Journal of Thermal Spray Technology, 2010
Cold gas dynamic spraying is a relatively new spray coating technique capable of depositing a variety of materials without extensive heating. As a result the inherent degradation of the powder particles found during traditional thermal spraying can be avoided. The simplicity of this technique is its most salient feature.

Development of Cold Gas Sprayed Coatings

International Thermal Spray Conference, 2003
Abstract By cold spraying, coatings are produced without significant heating of the spray powder and the substrate material. The powder particles are accelerated in a preheated gas stream to velocities of more than 500 m/s without melting and form a dense and tightly bonded coating.

Bonding mechanism in cold gas spraying

Acta Materialia, 2003
Cold gas spraying is a relatively new coating process by which coatings can be produced without significant heating of the sprayed powder. In contrast to the well-known thermal spray processes such as flame, arc, and plasma spraying, in cold spraying there is no melting of particles prior to impact on the substrate.
