Interplay between powder catchment efficiency and layer height in self-stabilized laser metal deposition
Simone Donadello, Valentina Furlan, Ali Gökhan Demir +1
In laser metal deposition (LMD) the height of the deposited track can vary within and between layers, causing significant deviations during the process evolution. Previous works ha…
Time-resolved quantification of plasma accumulation induced by multi-pulse laser ablation using self-mixing interferometry
Simone Donadello, Valentina Finazzi, Ali Gökhan Demir +1
In this work a method based on self-mixing interferometry (SMI) is presented for probing the concentration of plasma plumes induced by multi-pulse laser ablation. An analytical mod…
Plasticity and damage mechanisms in Ti-6Al-4V printed with selective laser melting
Atieh Moridi, Ali Gökhan Demir, Leonardo Caprio +3
The ability to create complex geometries with tailored material properties has brought interest in using additive manufacturing (AM) techniques in various industrial applications.…
Chromium Oxide Formation on Nanosecond and Femtosecond Laser Irradiated Thin Chromium Films
L. Kotsedi, V. Furlan, V. Bharadwaj +9
Thin coatings of Chromium oxide have been used for applications as absorbing material in solar cells, as protections for magnetic data recording devices and as shields in flexible…
Monitoring of laser metal deposition height by means of coaxial laser triangulation
Simone Donadello, Maurizio Motta, Ali Gökhan Demir +1
Laser metal deposition (LMD) is an additive manufacturing technique, whose performances can be influenced by several factors and parameters. Monitoring their evolution allows for a…
Probing multipulse laser ablation by means of self-mixing interferometry
Simone Donadello, Ali Gökhan Demir, Barbara Previtali
In this work, self-mixing interferometry (SMI) is implemented inline to a laser microdrilling system to monitor the machining process by probing the ablation-induced plume. An anal…
