The Analysis of Possible Application of Different Working Gases in Cold Gas Spray Method: Dynamics and Temperatures of Particles

Thermal spray (2014)

Aleksandra Małachowska A. Ambroziak B. Pateyron Lech Pawłowski

Abstract The paper analyzes different working gases and their mixtures for possible application in cold gas spraying (CGS). The gases considered include Ar, CO2, and steam, alone and in combination. Typical pressures and temperatures were used, along with CFD simulation software, to calculate gas velocity profiles along the axis of a convergent-divergent nozzle. The profiles are compared with that of nitrogen, the standard gas for cold spray, flowing under the same conditions. Velocity and temperature profiles were also calculated for copper particles in the various gas flows as well as nitrogen. Differences in temperature and velocity are explained based on sonic velocities, viscosities, and thermal conductivities of the respective gases.

Impedance spectroscopy of suspension plasma sprayed hydroxyapatite coatings

Optica Applicata (2009)

Tomasz Piasecki K. Nitsch Lech Pawłowski Roman Jaworski

Impedance spectroscopy was used to investigate the properties of hydroxyapatite (HA) coatings and their dependence on fabrication parameters. The HA layers were deposited on the titanium substrates using suspension plasma spraying. The analysis of the results was performed using equivalent circuit modelling. The HA layers contained crystalline and amorphous phases. The amount of amorphous phase raised with an increase of plasma torch power. The porosity of coatings was investigated by observation of water evaporation process. The conclusion was that samples fabricated with lower torch power had smaller and more complex pores structure.
