ITSC 2019, Thermal Spray 2019: Proceedings from the International Thermal Spray Conference, 678-681, May 26–29, 2019,
... Abstract Deposition efficiency is an important metric for thermal spraying, but it can be difficult to measure in some cases. In this study, a volume-based deposition factor is developed that can be used to estimate deposition efficiency simply by evaluating process parameters, coating...

... in typical plasma spray flows. Hence, they are swept away without depositing on the substrate. Analysis of inertial deposition reveals that the non-dimensional Stokes number largely characterizes deposition efficiency. Under low pressure plasma spray conditions, with reduced stand-off distance, the Stokes...

... deposition efficiency is of prime importance to shorten spray times. The optimisation of the gas composition in terms of viscosity and thermal conductivity (SPRAL 22) enables to increase dramatically this efficiency by 30% to 70%. Moreover, in order to reduce thermal expansion mismatch between substrate...
