High temperature oxidation and oxychlorination behaviors of cold sprayed Inconel 718 deposits at 700 °C
High temperature oxidation and oxychlorination behaviors of cold sprayed Inconel 718 deposits at 700 °C
The current research represents the first systematic study on high temperature oxidation and oxychlorination behaviors of cold sprayed Inconel 718. Tests were carried out at 700 ℃ and cold sprayed Inconel 718 was shown to possess excellent oxidation resistance comparable to that of the bulk Inconel 718. In the oxychlorination condition, a single-layer structure was observed in the scale of cold sprayed Inconel 718 in contrast to the double-layer scale in the bulk Inconel 718. Superior oxychlorination resistance of cold sprayed Inconel 718 was revealed and attributed to the much smaller grain size and higher dislocation density.

Abstract
The current research represents the first systematic study on high temperature oxidation and oxychlorination behaviors of cold sprayed Inconel 718. Tests were carried out at 700 ℃ and cold sprayed Inconel 718 was shown to possess excellent oxidation resistance comparable to that of the bulk Inconel 718. In the oxychlorination condition, a single-layer structure was observed in the scale of cold sprayed Inconel 718 in contrast to the double-layer scale in the bulk Inconel 718. Superior oxychlorination resistance of cold sprayed Inconel 718 was revealed and attributed to the much smaller grain size and higher dislocation density.
