The beneficial effect on lubrication achieved through microtexturing of sliding surfaces by laser ablation and polishing was investigated. The investigation was based on two independent experimental approaches with oil-lubricated smooth and laser-tex

This study reports the effect of nanoscaled surface structure of some hard coatings on the (micro-) frictional behaviour of systems under minimum lubrication conditions with modest contact pressures and low sliding speeds (below 1 mm/s). For this pur

The influence of nanoscale topography and chemical composition on microfriction has been studied at different humidities. Structured surfaces exhibit lower friction than smooth ones. Among the structured surfaces, the crater-like morphologies show lo

A key problem in microtribology is measurement equipment in the micronewton force regime. This work reports on a new generation of test devices for materials research that closes the gap existing between the so-called ‘macrotribometers’ and ‘na

This paper presents an overview of the microtribological properties of silicon oxide, sapphire, and titanium carbide surfaces as well as a self-assembled monolayer with respect to their application in microsystems. Testing was performed with a recipr

Co-sputtered thin films of MoS x with Ti were deposited in order to investigate the film’s tribological behaviour under various conditions. The mechanical properties of the composite films were investigated by pin-on-disk wear testing in air with 5

In this report, the influence of surface features in the nanoscale range on the hydrophobicity of fluoro-based polymer thin films was studied. For this purpose, poly[4,5 difluoro 2,2-bis (trifluoromethyl)-(1,3 dioxole)-co-tetrafluoroethylene] was dep

Crack-free and smooth surfaces of poly[4,5-difluoro 2,2-bis-(trifluoromethyl)-1,3 dioxole]-co-tetrafluoroethylene (TFE-co-TFD) films have been deposited by sol-gel technique on polished AISI 440C steel and quartz substrates. The deposited films have

Engineering of nanoparticles to detect ultraviolet light within a specified range and its feasibility to make a device has been demonstrated. It is shown that the absorption edge of a material can be shifted to significantly lower wavelengths in the
