| Abstract Scope |
Additive manufacturing (AM) of platinum alloys is of great interests for production of high temperature structural components for industrial and aerospace applications in aggressive atmospheres due to their simultaneous creep resistance and outstanding chemical stability, oxidation and corrosion resistance1. In here for the first time the potential for AM of Pt alloys for industrial applications was investigated. Laser Bed Powder Fusion (LBPF) was used to manufacture the test specimens for characterizations of density, hardness, ultimate tensile testing and oxidation rate at high temperature. The study illustrated the successful manufacture of fully dense parts. It was found that the LBPFed parts outperform that of the casted Pt-based alloys in terms of mechanical performance. Assessment of oxidation rate at high temperature of 1550°C demonstrated low level of weight change confirming their acceptable oxidation rate for final use at ultra-high temperatures.
