Dry-Sliding Wear Mechanisms of Shot-Peened Additive Manufactured Alpha Titanium Featuring TiB Particles

The load-induced dry-sliding wear behavior of alpha titanium (Ti) with low amount of boron ( 10 N), untreated samples experienced weight loss of the steel counterface balls and severe plastic deformation with the formation and onset delamination of mechanically mixed layers (MML). Comparatively, sho...

Description
Summary:The load-induced dry-sliding wear behavior of alpha titanium (Ti) with low amount of boron ( 10 N), untreated samples experienced weight loss of the steel counterface balls and severe plastic deformation with the formation and onset delamination of mechanically mixed layers (MML). Comparatively, shot-peened samples exhibited limited changes in wear behavior, remaining dominated by oxidation wear over the loading range. With oxidation wear dominating and the shot peening treatment inhibiting the formation of a MML and its delamination, it is hypothesized that the transition to severe wear may be delayed to higher loads from this treatment.
