Laser Structuring for Tribological Performance Enhancement

Tribological advancements for reliable wind turbine performance.

Wind turbines have had various limitations to their mechanical system reliability owing to tribological problems over the past few decades. While several studies show that turbines are becoming more reliable, it is still not at an overall acceptable level to the operators based on their current business models. Data show that the electrical components are the most problematic; however, the part...

Enhancing tribological performance of the magnetic tape/guide interface by laser surface texturing

Air-lubricated foil bearings are used in a variety of applications such as turbomachinery, journal bearings, dentistry equipment, etc. [1–3]. One of the most intricate applications of air-lubricated foil bearings can be found in magnetic tape drives [4], where a magnetic tape moves over a read/write head and tape drive components such as guides (stationary) and rollers (rotating). Friction is a...

Text Enhancement for Laser Copiers

The vast majority of copied documents generally consist of text, and the copy quality mostly depends on the text’s reproduction quality. A new technique to enhance dark text on light background of scanned mixed mode documents (containing text, graphics and photo) is presented to improve copy quality. This technique incorporates various image processing filters that enhance dark text without dis...

Laser surface structuring of AZ31 Mg alloy for controlled wettability.

Structured surfaces exhibit functional properties that can enhance the performance of a bioimplant in terms of biocompatibility, adhesion, or corrosion behavior. In order to tailor the surface property, chemical and physical methods can be used in a sequence of many steps. On the other hand, laser surface processing can provide a single step solution to achieve the designated surface function w...
