NiTi was surface treated with a pulsed Nd:YAG laser to accomplish oxidation without melting. The oxide layer was characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) to obtain information on the thickness, morphology, and the composition profile. The oxide...$28.00

Presented at ICALEO 2006
The FPD market continues rapidly growth. The panel manufacturer keeps an effort to increase the manufacturing efficiency, moreover must produce panels in consideration of global environmental concerns more than before. The laser patterning method is thought to be one of processing methods that breaks down the limit of a present manufacturing efficiency and environmental problems. Hitz Hitachi Zosen Co. and Takei electric industries Co., Ltd. have been developing various laser patterning equipments in FPD, semiconducto...$28.00

Presented at ICALEO 2006
Flat panel display manufacturing has recently been revolutionized by the industrial uptake of laser direct write techniques to replace lithography for patterning active thin films on glass. The use of diode pumped, high average power, nanosecond pulsed, kilohertz repetition rate infrared lasers to directly pattern electrically active thin films on glass substrates has elimina...$28.00

We report on the development of a novel laser-assisted microforming process for aluminum and stainless steel which makes use of localized 802-nm laser radiation to directly warm the area of the workpiece where the processing is to take place. The procedure makes use of sapphire dies structured using 266, 248 and 193-nm laser rad...$28.00

Presented at ICALEO 2006
Laser Forming (LF) is recognized as a novel technique with strong potential for industrial applications. This non-contact forming method is characterized by having no spring back effect. This very important feature gives LF industrial promise for many applications, especially rapid prototyping, precision adjustment, removing distortion and for generating 3D complex shapes, which can not be ac...$28.00

Laser shock peening by a micron sized laser beam is a process in which compressive residual stresses are induced in order to improve material fatigue life of micro scale components. The size of the laser target interaction zone is of the same order of magnitude as the target material grains and thus th...$28.00
