“…Summarily, the theoretical and experimental results have verified that in UPM crystallographic orientation significantly affects surface topography, cutting force and shear angle. More importantly, the periodical fluctuation of cutting force induced by crystallographic orientation leads to self-excited vibration (named [320] [100] [230]…”

“…Although mechanical machining, typically diamond cutting [12][13][14], has been widely used to fabricate micro/nanostructures on the surface of soft metals because of its flexibility, such as copper by tuning tool paths [15], it may be not suitable for MGs. The high hardness of MGs (usually 6-8 times of copper) accelerates the tool wear which affects the uniformity and accuracy of the cutting surface [16,17].…”

• Hierarchical micro/nanostructures were fabricated on a metallic glass substrate by nanosecond pulsed laser irradiation.• It retained amorphous characteristic and exhibited uniform element distribution.• Irradiation parameters induced change from cotton-like to particle-like nanostructure.• Formation mechanism and mechanical properties were investigated. A large effective surface area is beneficial to enhance the applications of metallic glasses (MGs) in heterogeneous catalysis and biomedical engineering. For the purpose of increasing effective surface area, in this study, hierarchical micro/nanostructures were fabricated on a Zr-based MG substrate by nanosecond pulsed laser irradiation. Experimental results indicated that a layer of micron-scale laser pulse tracks covered by a cotton-like MG thin film with nanometer-scale microstructure was formed in the laser irradiated region. This hierarchical micro/nanostructures retained amorphous characteristic and exhibited uniform element distribution. Its formation mechanism was investigated by analyzing the laser irradiation process and morphologies. Nanoindentation results indicated that the cotton-like MG thin film was very loose and soft compared to the as-cast MG substrate, showing different plastic deformation behavior. Results from this study indicate that nanosecond pulsed laser irradiation is an effective method to generate hierarchical micro/nanostructures on MG substrates, which can increase their effective surface areas and improve their potential applications as biomaterials and catalysts.

Nonlinear laser lithography to control surface properties of stainless steel

et al. 2015

In the present work a novel method to improve the surface properties of stainless steel is presented and discussed. The method, based on the use of a high repetition rate femtosecond Yb fibre laser, permits generation of highly reproducible, robust, uniform and periodic nanoscale structures over a large surface area. The technique is characterized by high productivity, which, in its most simple form, does not require special environmental conditioning. Surface morphology is scrutinized through SEM and AFM analyses and wettability behaviour is investigated by means of the sessile drop method using distilled–deionized water. It is shown that optimization of process parameters promotes anisotropic wetting behaviour of the material surface
