Abstract: Structural parts in gas turbines undergo fretting wear, and as clearances open up, it turns into impact wear. Uncoated cobaltbased substrates that are used in such applications show poor resistance to fretting/impact damage ...

Abstract: This research paper focuses on the fretting wear characteristics of self-mated laser powder bed fusion (L-PBF)-produced Inconel 718 alloy, with the primary aim of characterizing its distinct wear-rate in relation to fretting ...
