| Abstract Scope |
Materials with high temperature wear resistance are critical to the energy sector, such as the solar, wind, and oil and gas industries. The influence of additive manufacturing (AM) on the friction and wear behavior of several advanced Ni based alloys was investigated from room temperature up to 600°C in air using a pin-on-disk set up with an alumina counterpart. Novel alloys modified with oxide or nitride dispersoids, specifically for AM, were compared with unmodified compositions. Optical and electron microscopy, profilometry and Raman spectroscopy were used to characterize the wear track surfaces and cross-sectional microstructures. The microstructures, oxides (from tribocorrosion), friction coefficients and wear rates were correlated across the alloys and as a function of temperature to clarify the operating wear mechanisms. This ‘topAM’ project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 958192. |
