Moreover, the effect of the spraying process and the addition of alloying elements on the corrosion resistance of these coatings is also reviewed in this study (Fig. 4). 14 CHARACTERISTICS OF CONVENTIONAL AND CASCADED ARC PLASMA SPRAY-DEPOSITED CERAMIC UNDER STANDARD AND HIGH- THROUGHPUT CONDITIONS Ramachandran Chidambaram Seshadri and Sanjay Sampath Cascaded arc plasma torches with bothmultiple and sin- gle cathode configurations have become mainstream in the thermal spray industry. Although there are anecdotal descrip- tions available for cascaded arc torches in terms of enhanced melting capability and overall process reliability, a critical and direct comparison of material interaction between the two technologies (cascaded arc and conventional torch configu- rations) through robust scientific methods is not available. In this article, two commercially available APS torches, namely, the conventional torch (F4MB) and the cascaded arc plasma torch (Sinplex Pro), were compared in the same spray cell us- ing the same control equipment by adopting a systematic set of experiments involving voltage measurements, particle be- havior, deposit formation dynamics, and infrared-based spray footprint heat flux quantification. The analysis of the data has led to quantitative correlations between torch configurations. The powder loading study indicated the enhancedmelting ca- pability of cascaded arc at equivalent parameters along with expanded and more uniform particle temperature over larger feed rates. The combination of higher feed rate and melt effi- ciency leads to distinction in coating stress evolution and mi- crostructure. The integrated measurements suggest a scaling parameter that can establish process equivalency parameters to guide the transition from conventional to cascade torches (Fig. 5).
