Coating quality is affected by arc and plume instabilities during plasma spraying. In closed
chamber plasma spraying, gradual drift is one of the intermediate instabilities, which is …

In plasma spraying, instabilities and fluctuations of the plasma jet have a significant
influence on the particle in-flight temperatures and velocities, thus affecting the coating …

The natural instability of the are in direct current (DC) plasma torches used in spray
processing is one of the most important causes for variations in heating of sprayed particles …

Despite the fact that plasma spraying has been a widely used technology over the past three
decades, industries using this technology still need higher quality products. Presently, only a …

A novel atmospheric plasma spray method was proposed, using a newly development direct
current non-transferred arc plasma torch which generated a long, stable and silent plasma …

Plasma spraying using liquid feedstock allows realizing thin coatings (< 100μm). In this
process, the plasma jet fluctuations play an important role in the behavior of the liquid …

In plasma spray, operation parameters, including current, flow rate of primary gas, and flow
rate of secondary gas, would influence the heat and acceleration status of particles greatly …

The quality of a plasma sprayed coating is influenced by the plasma jet stability; entrainment
of cold air through large scale turbulence can lead to variations in particle heating and …

Plasma spray-physical vapor deposition (PS-PVD) is an emerging technology for the
deposition of uniform and large area coatings. As the characteristics of plasma jet are …

Acrylic polyurethane paint on the surface of 2A12 Al alloy was cleaned utilizing an
atmospheric pressure plasma jet in this work. The dynamic evolution of the paint removal …
