Deposition of brass coating by a method of cold gas-dynamic spraying

Physics and Chemistry of Materials Treatment, 2020
The structure and properties of a coating based on a mechanical mixture of Cu and Zn particles deposited on a steel substrate by gas-dynamic spraying are studied. X-ray diffraction and microspectral analysis show a significant effect of the deposition temperature on the content of Cu and Zn in the coating. When the deposition temperature increases from

Deformation Microstructure of Cold Gas Sprayed Coatings

MRS Proceedings, 2001
ABSTRACTCold Gas Spraying is a new coating technique, in which the formation of dense, tightly bonded coatings occurs only due to the kinetic energy of high velocity particles of the spray powder. These particles are still in the solid state as they impinge on the substrate.

Atomistic simulations of interfacial deformation and bonding mechanism of Pd-Cu composite metal membrane using cold gas dynamic spray process

Vacuum, 2020
The creation of atomic structures and the study of the deformation processes through molecular dynamics simulations have shown many advantages. However, gaps associated with the development and evolution of microstructure in the coating zone and dynamic ...

HVOF K2 vs. Cold Gas Spraying

International Thermal Spray Conference, 2011
Abstract A conventional GTV K2 kerosene fuel HVOF spraying system has been modified with the aim to achieve process conditions comparable to cold gas spraying concerning the average particle velocities and surface temperatures in the spray distance.

Influence of spraying parameters on cold gas spraying of iron aluminide intermetallics

Surface and Coatings Technology, 2015
Abstract Cold spraying was used to build up coatings of ordered Fe40Al intermetallics, which are a kind of alloys which are being proposed for high temperature applications. The spray experiments were performed with chemically ordered powder feedstock of different size distributions to study influences from impact velocities.

Investigation of gas flow through a mask at cold spraying

AIP Conference Proceedings, 2020
The article presents an investigation of gas flow that occurs under typical for cold spraying conditions when supersonic gas jet, that exhausts from De Laval nozzle, and impinges on mask with a round perforation, behind that substrate is placed. Numerical simulation was made using software ANSYS Fluent. Shadowgraph was used to obtain images of gas flow.

A perspective review on the bonding mechanisms in cold gas dynamic spray

Surface Engineering, 2018
The Cold Gas Dynamic Spray technology, generally referred as Cold Spray, is a relatively new additive manufacturing technique able to produce fully dense coatings through the deposition of particles on a substrate.
