| Abstract Scope |
This study investigates the synergistic effects of wear and corrosion on Wire Directed Energy Deposited (WDED) commercially Pure Titanium (cp-Ti). Understanding this interaction is crucial for ensuring the durability of additively manufactured (AM) materials subjected to mechanical friction in harsh environments. Initial findings indicate that the tribocorrosion performance of cp-Ti WDED is comparable to traditionally manufactured hot-rolled titanium in a neutral pH aqueous electrolyte, with wear volumes of 194.1×10⁻⁵ ± 20.1×10⁻⁵ mm³/Nm and 181.7×10⁻⁵ ± 1.8×10⁻⁵ mm³/Nm, respectively. No corrosion products were found on the groove due to the immediate repassivation of the worn surface. Current studies aim to determine the independent effects of mechanical and electrochemical actions on the cp-Ti WDED by subjecting the specimen under ball-on-disk tests in NaCl electrolyte at varying loads (2-20 N). Understanding the effect of corrosive wear on cp-Ti WDED performance significantly contributes to the advancement of large-scale additive-manufactured materials. |
