Cytocompatibility of Direct Laser Interference-patterned Titanium Surfaces for Implants [PDF]

In Vivo, 2018
In an effort to generate titanium surfaces for implants with improved osseointegration, we used direct laser interference patterning (DLIP) to modify the surface of pure titanium grade 4 of four different structures. We assessed in vitro cytoxicity and cell attachment, as well as the viability and proliferation of cells cultured directly on the ...

Multi-Scale Structuring of CoCrMo and AZ91D Magnesium Alloys Using Direct Laser Interference Patterning

Metals, 2023
In this work, the technique of Direct Laser Interference Patterning (DLIP) was used to fabricate micrometric structures at the surface of Cobalt-Chromium-Molybdenum and AZ91D magnesium alloys. Line-like patterns with spatial periods of 5 μm were textured

Advanced remote laser cutting of battery foils using an interference approach

Materials Letters: X, 2022
This work demonstrates how an interference pattern can improve the performance of remote laser cutting of pure copper foils, making the cutting process effective even for a low power laser source. The proof of concept is carried out by using a nanosecond

Monitoring the Heat Accumulation during Fabrication of Surface Micro-patterns on Metallic Surfaces Using Direct Laser Interference Patterning

, 2020
Metallic samples with unique micro- and nano-scale surface structures can easily be fabricated with Direct Laser Interference Patterning. Like in all laser processes, the material interacts with the laser radiation and as a result, thermal effects occur.

Effect of Low Depth Surface Texturing on Friction Reduction in Lubricated Sliding Contact

Lubricants, 2018
Laser surface texturing is an interesting possibility to tailor materials’ surfaces and thus to improve the friction and wear properties if proper texture feature sizes are selected.

WO3 processed by direct laser interference patterning for NO2 detection [PDF]

Sensors and Actuators B: Chemical, 2020
In this paper two kind of sensors based on WO3 sputtered by magnetron sputtering and annealed at 600 degrees C have been studied. The first kind was processed by two-dimensional direct laser interfering patterning (DLIP) and the second one without any additional treatment.
