“…Pan et al created different surface morphologies with fs lasers to improve the poor tribological performance. The 68.9% coefficient of friction to 90% wear reduction achieved is based on the increased microhardness resulted by the laser shock peening, the titanium-oxide formation on the surface and the beneficial effect of the surface modification [41].…”

The internal combustion engine will be required as a bridge-technology in the upcoming decades to achieve a significant reduction in local emissions in the mobility, and logistics sector. Alternative fuel technologies will present new mechanical engineering challenges, including increasing efficiency and reducing mechanical losses. Textured surfaces with appropriate manufacturing parameters can enhance lubrication, and reduce friction in sliding and rolling contacts, e.g., journal bearings, or the piston ring -cylinder subsystem. This paper gives an overview of 80 scientific works related to laser surface technologies, with an emphasis on surface texturing for friction reduction from the viewpoint of engine development. The most common texture types, further directions, and general challenges are highlighted in the summary.

“…Cutting parameters were examined in relation to tool wear, force of cutting, and surface roughness. In terms of polishing PTMCs, it was observed that the brazed CBN wheel had an advantage over the electroformed CBN wheel [18,19] for its machinability. Te efect of factors on performance metrics and the built-up edge and chip creation are studied during turning operations.…”

ZrB2 particle-reinforced AA7475 is a potential material for high-performance aeronautical engine blades because of its exceptional characteristics. The machinability of ZrB2/AA7475 metal matrix composites (MMC) is still a challenge because of the influence of ZrB2 particles. The impact of ZrB2 particulates on the machined parameters of ZrB2/aluminum matrix composites was explored experimentally in order to meet the needs of industry. Additionally, the best machining circumstances for this type of material matrix composites were studied in this research. A surface roughness (Ra) and metal removal rate (MRR) multiobjective optimization model was built, and a set of ideal parameter combinations was produced, with the surface roughness of ZrB2/AA7475 material matrix composites being lower than that of the nonreinforced alloys at the same cutting speed.

“…For example, Pan et al explored the ultra-short laser modifications of a titanium alloy as a tool to improve anti-friction properties of the material. With laser power spanning 10 to 240 μJ (λ = 1064 nm, τ = 290 fs) the researchers induced periodic surface microstructures with an outer layer of titanium oxide which led to a sharp decrease in the coefficient of friction and wear mass loss [4]. An important field that ultrashort lasers are gaining popularity in is tissue engineering.…”

The application of ultra-short lasers pulses in surface modification has gained a significant interest as they allow precise patterning of materials without inducing any collateral thermal damages. Tricalcium phosphate (TCP) is a widely exploited material for scaffolds in bone tissue engineering; however, such composites could lack the appropriate porosity that is crucial for the tissue regeneration process. This article presents a combination of fabricating porous ceramic scaffolds and their processing by a femtosecond (fs) laser for enhancement of the surface properties. The morphological observation revealed evident differences on the exterior of the treated zones, as the dense structure was preserved but the porosity of the surface appeared improved. An X-ray diffraction analysis showed that the laser treatment increased the crystallinity of ZrO2 and TCP, thus stabilizing the material. The laser-induced surface microporosity substantially changed the wetting state of the scaffolds’ surfaces making them hydrophilic. Based on these findings, we could state that the femtosecond laser processing of TCP-ZrO2 composites could have the potential to improve their applications in fields such as bone tissue engineering.
