Condition: Hervorragend. Zustand: Hervorragend | Seiten: 52 | Sprache: Deutsch | Produktart: Bücher | Dieses Buch beschreibt die Verwendung von Femtosekundenlaserpulsen in Kombination mit trockenen und verschiedenen flüssigen Umgebungen. Es befasst sich mit der Entwicklung von Mikro-/Nanostrukturen, Veränderungen der Kristallinität und der Nanohärte nach der Wechselwirkung von Femtosekundenlaserpulsen mit der Silberoberfläche. Die Bildung von Silberoxid, Silberhydrid und Silberhydroxid aufgrund der Erhöhung der chemischen Reaktivität von Silber nach Femtosekunden-Laserbestrahlung wird in Korrelation mit den Oberflächen- und mechanischen Eigenschaften diskutiert. Zu diesem Zweck wurden Silber-Targets mit Ti:Saphir-Lasern für eine unterschiedliche Anzahl von Laserpulsen in Umgebungen mit Luft, Ethanol, Propanol und de-ionisiertem Wasser abgetragen. Verschiedene Diagnosetechniken wie Rasterelektronenmikroskop (SEM), energiedispersive Röntgenspektroskopie (EDS), Röntgendiffraktometrie (XRD), Raman-Spektroskopie und Nanohärte-Testtechniken wurden eingesetzt, um die Variationen in der Kristallinität und der chemischen Zusammensetzung der Oberfläche mit den Oberflächenmerkmalen und der Nanohärte nach der Interaktion mit Femtosekunden-Laserpulsen zu korrelieren. …

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book describes the generation of femtosecond laser induced structuring of Stainless steel in different environments (vacuum & O2) for various laser fluences. The irradiated targets were analyzed by using various characterization techniques. Surface damage morphology with fluence, shot number and ambient environment are investigated by using SEM analysis. The chemical and phase analysis is performed by using EDS and XRD analysis. It describes a strong correlation between surface morphology, chemical analysis and with the evolution of stresses under both ambient environments. It is observed that the fsec laser produces a large variety of nano/ micro-structures i.e., LIPSS formation parallel and perpendicular to the incident laser field, micro-cones and micro-cavities. This book gives a comprehensive insight to the mechanisms and physical processes that are responsible for forming such structures in metals. It also presents optimal threshold values for producing these surface and structural modifications, respectively. 68 pp. Englisch.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book describes the use of a femtosecond laser pulses in combination with dry and various liquid environments. It deals with the evolution of micro/nanostructures, variations in crystallinity and nanohardness after interaction of femtosecond laser pulses with silver surface. Formation of silver oxide, silver hydride and silver hydroxide due to enhancement of chemical reactivity of silver after femtosecond laser irradiation is discussed in correlation with the surface and mechanical properties. For this purpose silver targets were ablated with Ti: sapphire laser for various number of laser pulses in ambient environments of air, ethanol, propanol and de-ionized water. Various diagnostic techniques like Scanning Electron Microscope (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), X-Ray Diffractometery (XRD), Raman Spectroscopy and nanohardness testing techniques were employed to correlate the variations in crystallinity and surface chemical composition with the surface features and nanohardness after interaction of femtosecond laser pulses.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Ce livre décrit l'utilisation d'impulsions laser femtoseconde en combinaison avec des environnements secs et divers environnements liquides. Il traite de l'évolution des micro/nanostructures, des variations de la cristallinité et de la nano-dureté après l'interaction des impulsions laser femtoseconde avec la surface de l'argent. La formation d'oxyde d'argent, d'hydrure d'argent et d'hydroxyde d'argent due à l'augmentation de la réactivité chimique de l'argent après irradiation par laser femtoseconde est examinée en corrélation avec la surface et les propriétés mécaniques. Pour ce faire, des cibles d'argent ont été ablatées avec un laser Ti : saphir pour différents nombres d'impulsions laser dans des environnements ambiants d'air, d'éthanol, de propanol et d'eau désionisée. Diverses techniques de diagnostic telles que le microscope électronique à balayage (MEB), la spectroscopie X à dispersion d'énergie (EDS), la diffractométrie X (XRD), la spectroscopie Raman et les techniques de test de nano-dureté ont été employées pour corréler les variations de la cristallinité et de la composition chimique de la surface avec les caractéristiques de la surface et la nano-dureté après l'interaction des impulsions laser femtoseconde.…
