Cold Gas Dynamic Spray (CGDS) Technology and Applications
Academic Platform Journal of Engineering and Science, 2013 Thermal spray coatings are obtained by sending powder particles with high heat and/or kinetic energy onto a target substrate material in molten or semi-molten form. Nowadays, thermal spray coatings are used in many areas such as particularly aviation and defense industry and also energy, electronic and biomedical applications.

Simulation of gas-substrate heat exchange during cold-gas dynamic spraying
International Journal of Thermal Sciences, 2012 Abstract In this study, the Nusselt numbers of impinging compressible fluid jets originating from a cold-gas dynamic spraying nozzle were determined. A low-pressure cold-gas dynamic spraying unit was used to generate a jet of hot compressed nitrogen that impinged upon flat substrates.

Analysis of De-Laval nozzle designs employed for plasma figuring of surfaces [PDF]
, 2016 Plasma figuring is a dwell time fabrication process that uses a locally delivered chemical reaction through means of an inductively coupled plasma (ICP) torch to correct surface figure errors. This paper presents two investigations for a high temperature

The Problem of Copper Softening During Cold Gas Dynamic Spraying [PDF]
Coatings, 2019 The effect of the gas-dynamic (cold) spraying of the Cu-Al2O3-Zn powder mixture on the microstructure and strength of the copper substrate is investigated. A copper cold drawn contact wire was used as a substrate. We propose using gas-dynamic cold spraying to restore the local wear of the contact wire. The study of the microstructure using the electron

Modelling of gas permeation through ceramic coatings produced by thermal spraying
, 2008 An analytical model has been developed for simulation of gas permeation through thermal spray coatings, and for prediction of the permeability. The model is based on a geometrical representation of the coating microstructure.
