Abstract Scope |
Understanding the high temperature tribological behavior of materials is crucial for applications in the aerospace, transportation, and energy generation industries. The friction and wear behavior of conventionally processed and additively manufactured (AM) Ni-based alloys 699XA and 400 was investigated by pin-on-disk tribotesting against an alumina counterpart at room temperature and up to 600°C in air. The wear tracks were examined using optical microscopy, scanning electron microscopy, profilometry and Raman spectroscopy on the surface and in cross-section. The microstructures and surface oxides of the conventional versus AM alloys are compared and correlated to the friction coefficients and wear rates as a function of temperature. The trends are discussed in terms of their mechanisms and the potential for improving the wear behavior of these types of Ni-based alloys. This ‘topAM’ has project received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 958192. |
