This paper evaluates two CFD tools for predicting particle speeds and temperatures during atmospheric plasma spraying. The investigation is based on varying two parameters: plasma current and gas flow rate. Although the tools differ in accuracy, both proved to be sufficient for optimizing industrial plasma spraying processes. A comparison of the results with experimental data showed the more advanced tool to be capable of predicting variations in particle characteristics when operating conditions change. Paper includes a German-language abstract.
