Surface integrity of additive manufacturing parts: a comparison between optical topography measuring techniques

Tato Vega, Wilson; Llavori, Inigo; Aginagalde, Andrea; Zabala, Alaitz (Elsevier B.V., 2020)

Additive Manufacturing (AM) presents significant industry-specific advantages allowing the creation of complex geometries and internal features that cannot be produced using conventional manufacturing processes. However, ...

On the Role of a ZDDP in the Tribological Performance of Femtosecond Laser-Induced Periodic Surface Structures on Titanium Alloy against Different Counterbody Materials

Ayerdi Gómez, Jon Joseba; Llavori, Inigo; Zabala, Alaitz; Aginagalde, Andrea (MDPI, 2019)

Laser-induced periodic surface structures (LIPSS, ripples) with ~500–700 nm period were produced on titanium alloy (Ti6Al4V) surfaces upon scan processing in air by a Ti:sapphire femtosecond laser. The tribological ...

Ball-on-flat linear reciprocating tests: Critical assessment of wear volume determination methods and suggested improvements for ASTM D7755 standard

Ayerdi Cantalejo, Jon; Aginagalde, Andrea; Llavori, Inigo; Zabala, Alaitz (Elsevier B.V., 2021)

This work presents a critical assessment of wear volume determination methods for ball-on-flat linear reciprocating sliding tribological tests. It revealed that the ASTM D7755-11 standard leads to the highest relative ...

The Interaction between the Sheet/Tool Surface Texture and the Friction/Galling Behaviour on Aluminium Deep Drawing Operations

Zabala, Alaitz; GALDOS, Lander; Llavori, Inigo; Aginagalde, Andrea; Mendiguren, Joseba; Sáenz de Argandoña, Eneko (MDPI, 2021)

The increasing demands for lightweight design in the transport industry have led to an extensive use of lightweight materials such as aluminium alloys. The forming of aluminium sheets however presents significant challenges ...
