Cover Story: In this work, we present a thermal model that predicts the temperature distribution at different substrate depths during the APS coating process, taking into account the effect caused by flame profiles. We define the heat flux contributed by the plasma plume to fit the simulation results with the experiments. The simple and low-cost experimental procedure measures the plasma plume temperature distribution of the APS coating arrangement, and results are then used to obtain the parameter values of each of the three proposed plasma temperature profiles. We demonstrate the approach on a thermal simulation model of a flat plate with three proposed flame plume profiles and compare the results with experimental data obtained using an in situ non-contact infrared pyrometry method.
