Reduction of friction at very low normal loads and for very small contact areas is important for the development of micro devices. High performance hard coatings such as diamond-like carbon (DLC) films and improved surfaces with nanostructures are be

Two types of laser-induced periodic surface structures (LIPSS) formed on titanium by femtosecond (fs) laser pulses (λ = 800 nm, τ = 180 fs, ν = 1 kHz) in air were investigated experimentally. At a laser fluence F above the ablation threshold, LIPS

Two types of diamond-like carbon (DLC) thin films, hydrogenated amorphous carbon (a-C:H) and super-hard tetrahedral amorphous carbon (ta-C), were irradiated with femtosecond laser pulses, and the corrosion resistance of the DLC films with laser-induc

Femtosecond (fs)-laser-induced nanostructuring of mainly nitrided die steel (1.5C-12Cr) was experimentally investigated using die steel that was heat-treated and then plasma nitrided. Nitrided stainless steel (18Cr-8Ni) and low-carbon steel (0.1C) we

Periodic surface nanostructures formed on nitrided stainless steel with femtosecond (fs) laser pulses were investigated and compared with those of an untreated surface. The nanostructures are formed in the direction perpendicular to the laser polariz

This paper reports tribological properties of diamond-like carbon (DLC) films nanostructured by femtosecond (fs) laser ablation. The nanostructure was formed in an area of more than 15 mm × 15 mm on the DLC surface, using a precise target-scan syste
