Corrosion inhibitors are an important method for minimizing corrosion; however traditional inhibitors such as chromates pose environmental problems. Rare earth metals provide an important, environmentally-friendly alternative. This book provides a comprehensive review of current research and examines how rare earth metals can be used to prevent corrosion and applied to protect metals in such industries as aerospace and construction. Chapter 1 begins by examining the important need to replace chromate, and then goes on to discuss the chemistry of the rare earth metals and their related compounds. Chapter 2 considers the techniques that can be used to identify corrosion inhibition mechanisms and to test the levels of protection offered to different metals by rare earth compounds. Subsequent chapters consider in more detail how rare earth elements can be used as corrosion inhibitors in different forms and for different metals. This includes discussion on the potential of rare earth elements for self-healing, tunable and multifunctional coatings. Finally, chapter 10 considers the cost and availability of the rare earths and the potential health and environmental risks associated with extracting them.

Nanotechnologie gilt als eine der Schlüsseltechnologien des 21. Jahrhunderts mit stark wachsender wirtschaftlicher Bedeutung. In Architektur und Bauwesen liegen ihre heute nutzbaren Potenziale besonders in der Beschichtung von Oberflächen, die diesen funktionale Eigenschaften wie erhöhte Bruchfestigkeit, Fähigkeit zur Selbstreinigung, Feuerresistenz etc. verleiht. Auf Nanomaterialien basierende Zusatzstoffe machen gängige Materialien leichter, durchlässiger oder verschleißfester. Nicht nur für Fassaden und Dächer sind Nanomaterialien von großem Interesse, sondern sie bereichern auch die Gestaltungsmöglichkeiten von Innen- und Außenräumen. Nano-Dämmmaterialien eröffnen ökologisch ausgerichteten Architekten neue Potenziale. Architekten, Innenarchitekten und Designer finden in diesem Buch eine auf ihre Belange zugeschnittene Einführung in den naturwissenschaftlichen Hintergrund, eine kritische Diskussion der Vorzüge und Grenzen dieser Technologie und vor allem eine umfassende, mit zahlreichen internationalen Projektbeispielen belegte Darstellung von 16 bau- und designrelevanten Eigenschaften und Funktionen von Nanomaterialien.

This book intended for shop use tries to familiarize the reader with the peculiari ties of a hardening method which due to its many advantages is now in use,many shops. A general knowledge of the principles of hardening and heat treating is presumed. Introduction 1. The name of the process. Flame hardening is a method derived from the old quench hardening and is used for the surface hardening of heat treatable steels. Flame hardening is so named in analogy to flame cutting as the use of a flame is a distinctive feature of this process as opposed to the use of a furnace. 2. Characteristics of flame hardening. In flame hardening the area to be 6 hardened is heated with a burner of large heat capacity (approx. 0.5 · 10 kcaljhr/ meter of flame lengths or 50,000 BTUfhr/inch of flame length) supplied with a mixture of fuel gas and oxygen. The hardening temperature is thus reached in so short a time at the surface that a heat jam is created, that is, more heat is supplied to the surface than can be dissipated to the interior of the workpiece. As the querr ehing takes place immediately after the heating the penetration of the heat to greater depth is prevented and only the outer layer subject to wear is hardened. The core of the workpiece remains unaffected by this heat treatment in cantrast to the other hardening methods where the entire piece is through heated in a furnace.

Seit dem Erscheinen der ersten Auflage vor fast 30 Jahren ist das Handbuch des kathodischen Korrosionsschutzes zu einem Klassiker geworden. Der Erfolgstitel liegt nun in der vierten Auflage vor. Kathodischer Korrosionsschutzes hat in den vergangenen Jahren nichts an seiner Bedeutung verloren - er ist auch heute noch eines der wichtigsten Verfahren des Korrosionschutzes uberhaupt. Auf einigen Gebieten wie dem Schutz von Stahlbeton ist seine Bedeutung sogar noch gewachsen. Gut zehn Jahre nach dem Erscheinen der dritten Auflage musste in vielen Bereichen eine Neubearbeitung durchgefuhrt werden. Das gilt - wie bereits bei fruheren Auflagen - fur die Messtechnik zum Nachweis der ausreichenden Schutzwirkung mit der praktischen Anwendung bei Rohrleitungen und Fragen der Beeinflussung durch Gleichstrome sowie die Wirkung von Wechselspannungen. Im Bereich der Korrosion bilden die verschiedenen Arten der Risskorrosion und die Wechselstromkorrosion Schwerpunkte der Uberarbeitung. Auf dem Gebiet der Messtechnik und der Umhullungsschaden wurden neuartige Beschriebungen der elektrischen Eigenschaften von Beschichtungsfehlstellen entwickelt. Die vierte Auflage erscheint in einer Zeit der verstarkten internationalen Zusammenarbeit - insbesondere bei der Normung - und eines zunehmenden Sicherbeitsbedarfs. Deshalb dient das Handbuch auch der Wissenserhaltung mit allen zugehorigen Grundlagenwissenschaften und gegebenenfalls auch zur Basis von Qualifikationsnachweisen. Wieder haben zahlreiche Fachleute aus der Industrie ihr Fachwissen zum weltweit einzigartigen Standardwerk uber alle Anwendungsbereiche der elektrochemischen Korrosionsschutzverfahren beigetragen. Dabei wurde Wert auf luckenlose Querverweise zwischen den einzelnen Kapiteln und einheitliche bzw. normgerechte Terminologie gelegt. Das Handbuch ist nicht nur unentbehrlich fur Unternehmen fur kathodischen Schutz, sondern ist fur alle Personen, die sich mit Korrosion und Korrosionsschutz beschaftigen, zum Nachschlagen und zur Weiterbildung geeignet.
