International audienceSuspension plasma spraying (SPS) permits to manufacture finely structured coatings (nano- or submicron-sized) coatings. Compared to conventional plasma spraying, SPS exhibit several major differences: i) a more pronounced sensitivity to arc root fluctuations; ii) a shorter spray distance; iii) a higher thermal flux transmitted from the plasma flow to the substrate. Several operating parameters play relevant roles in the suspension processing and the coating architecture
