Sensitization of AISI 302 stainless steel during low-power laser forming
(ELSEVIER SCI LTD, 2010)
Low-power laser forming by raster scanning is a promising technology for shaping thin sheets in a non-contact manner, using a laser beam scanned over the surface. In this work, the change of material microstructure and the ...
Effect of the Nd:YAG and the Er:YAG laser on the adhesive-dentin interface: a scanning electron microscopy study
(Mary Ann Liebert, Inc.Porto Alegre, 2010)
Objective: This study analyzed the adhesive-dentin interface when Nd:YAG and Er:YAG lasers were applied on dentin. Background data: Lasers applied on dentin cause morphological changes of this tissue. As the adhesive systems ...

Bending of stainless steel thin sheets by a raster scanned low power CO2 laser
(ELSEVIER SCIENCE SA, 2009)
Laser forming of thin metal sheet plates using a low output power CO2 laser has been successfully performed using a mirror based scanning system. Graphite coated AISI 302 stainless steel plates, 0.3 mm thick, have been ...
Investigation of the metal/porcelain interface in LASER-welded Ni-Cr-Mo alloy
(2009-07-22)
The interface formed between the metal and the porcelain of laser-welded Ni-Cr-Mo alloy was studied on a metallurgical basis. The characterization was carried out by using optical microscope, electron scan microscopy and ...
