Abstract Titanium alloys are widely used in demanding applications due to their exceptional strength-to-weight ratio, high-temperature resilience, and excellent corrosion resistance. Understanding tribological behavior is critical, as the performance durability of several mechanical systems, particularly gas turbine engines, often constrained by friction wear complex contacting mobile assemblies. This study investigates two titanium alloys, Ti–6–4 Ti–6–2–4–2, focusing on interfacial phenomena under varied operational conditions. Tribological testing was conducted using a reciprocating tribometer at different temperatures loading Ex situ analyses revealed that mechanisms were heavily influenced properties oxide layer formed during sliding. Under higher loads, alloy surface fractured, resulting generation flake-like debris, which contributed third-body abrasion. Additionally, examined transfer film formation alumina counterface various conditions, correlating friction, with processes, worn surfaces. enhances understanding paving way for improved through advanced modification techniques.
