	Numerické modelování zbytkového napětí v materiálu při laserovém svařování Chmelíčková, Hana ; Havelková, Martina ; Lapšanská, Hana Laser welding method is widely used in the industrial production, from micro welding of electronic parts to joining automobile and aeroplane parts. Distribution of temperature field in narrow heat affected zone and following mechanical deformation and residual stresses of part can be modelled by FDM numerical software SYSWELD. Detailed record
	SYSWELD welding simulation Lapšanská, Hana ; Chmelíčková, Hana ; Havelková, Martina ; Čtvrtlík, Radim This contribution informs about proram SYSWELD.sup.®./sup. 2004 which is used for simulations of some physical and chemical events running in materials during processes connected with heat conduction, especially during welding. Detailed record
	Svařování cylindrických profilů pulsním laserem Čtvrtlík, Radim ; Havelková, Martina System KLS 246-102 is a high power pulsed Nd:YAG laser, which is suitable for welding of metal materials, thickness up to 1 mm. Performed experiments of cylindrical profiles welding are comleted by simulation made by program SYSWELD Detailed record
	Laserové řezání CVD diamantových plátků Chmelíčková, Hana ; Stranyánek, Martin ; Rosa, Jan ; Vaněček, Milan CVD diamond wafers with diameter 51 mm and thickness from 0,1 mm to 0,7 mm are necessary to cut to different shapes. Cutting technology by means of pulsed Nd:YAG laser was developed to successful dividing of thin pieces Detailed record
	Výsledky mikroanalýz Ni-Cr-si struktur laserových povlaků Stranyánek, Martin ; Chmelíčková, Hana ; Hrabovský, Miroslav Studied structures were produced by Ni-based alloy laser cladding on ČSN 411 373 steel using CO.sub.2./sub. laser. Some verification of process parameters and material distribution in clad layer were analysed by SEM Detailed record
	Study on material composition in the layer of coat produced by laser Stranyánek, Martin The article deals with investigation of layers produced by the laser cladding technology from viewpoint of material changes in treated area. The elements distribution was studied by scannig electron microscopy. Detailed record
	The evaluation of the dentine surface by means of SEM & AFM after previous exposure to Nd:YAG laser Novotný, R. ; Zapletalová, Z. ; Kubínek, R. ; Chmelíčková, Hana ; Peřina st., Jan Dentine sensitivity is a common complaint of patients in dental offices. It is caused by the opening of dentine tubules towards the external environment. One of the procedures that seems to have a longer-lasting effect is the closure of the exposed dentinal tubules on the teeth surface by means of CO 2 laser or Nd:YAG laser. Detailed record
	The evaluation of the dentine surface by means of SEM & AFM after previous exposure to ND:YAG laser Zapletalová, Z. ; Peřina st., Jan ; Novotný, R. ; Kubínek, R. ; Chmelíčková, Hana Dentine senzitivity is a common complaint of pacients in dental offices. They are caused by the opening of dentine tubules. This may be due to enamel or cementum loss or due to the dentine exposure in the area of cementum-enamel junction. A procedure with long-lasting effect seems to be the closure of the exposed dental tubules on the teeth surface by means of CO 2 or ND:YAD laser. Detailed record
