| Abstract Scope |
A novel Al-Ce-Mo alloy developed for laser powder bed fusion additive manufacturing was tested for application in high speed, oxidative gas flows at elevated temperatures and pressures. Both a wall-mounted ramp geometry and a centrally mounted wedge geometry were instrumented for temperature and pressure measurement throughout. The wall-mounted ramps showed only minor degradation of the surface after testing at airflow in excess of 1,715 m/s along with no discernable changes in microstructure. The wedge samples, which experienced a higher surface temperature due to the flow around the sample, exhibited ablation of the leading edge. Results of this testing, as well as comparative testing with additively manufactured and cast Al F357 and 316L stainless steel are discussed. |
