This paper discusses the requirements of sensors that could be used both for advanced real-
time control as well as manual torch operator control of plasma spray processes, and …

The plasma-spray process features complex plasma-particle interactions that can result in
process variations that limit process repeatability and coating performance. This paper …

Substrate temperature variation was measured during plasma spraying of ZrO 2 7% Y 2 O 3
powder using fast-response thermocouples embedded in the stainless steel surface …

Abstract Lanthanum zirconate (La 2 Zr 2 O 7) has been proposed as a promising material for
thermal barrier coatings. During atmospheric plasma spraying (APS) of La 2 Zr 2 O 7 a …

Controlling particle state is important to not only achieve the required microstructure and
properties in coatings but also to clearly isolate and understand the role of other clusters of …

In-flight particle state parameters (PSPs) have been shown to play a crucial role in
determining the properties of atmospheric plasma-sprayed coatings. Therefore, PSPs are …

The interdependence between plasma spray process parameters and porosity of YSZ
coating microstructures was investigated with simultaneous consideration of the deposition …

Over the last decade there has been an explosion in terms of available tools for sensing the
particle spray stream in thermal spray processes. This has led to considerable enhancement …

The standards of quality in the aerospace industry require a precise control of the thermal
spray process to insure a good reproducibility of the coating characteristics. Even if the …

The effect of various small-particle plasma spray powder injection parameters on the in situ
particle position, velocity, and temperature is measured for yttria-stabilized zirconia and …
