Book Description :

An important brazing application is the production of cutting and machining tools. This chapter provides an overview of brazing alloys for the joining of cutting materials. Process-related problems and solutions are presented and discussed. High strength values can be achieved with the right filler alloy and joint design. Most cemented carbides consist of a hard material such as tungsten carbide and a metallic binder. Due to the high carbide content, wetting and bonding reactions have to be monitored. Addition of active elements can help to induce a wetting reaction. Brazing ceramic cutting materials requires the use of active filler alloys to achieve a wetting reaction. The chapter reviews the alloys required. A joint can be weakened by interfacial effects or mismatches in physical properties. Employing the right filler metal with an adapted brazing process can significantly improve joint quality. Stress calculations based on the finite element method contribute to better joint design with reduced stress levels.

Book Description :

Brazing processes offer enhanced control, adaptability and cost-efficiency in the joining of materials. Unsurprisingly, this has lead to great interest and investment in the area. Drawing on important research in the field, Advances in brazing provides a clear guide to the principles, materials, methods and key applications of brazing. Part one introduces the fundamentals of brazing, including molten metal wetting processes, strength and margins of safety of brazed joints, and modeling of associated physical phenomena. Part two goes on to consider specific materials, such as super alloys, filler metals for high temperature brazing, diamonds and cubic boron nitride, and varied ceramics and intermetallics. The brazing of carbon-carbon (C/C) composites to metals is also explored before applications of brazing and brazed materials are discussed in part three. Brazing of cutting materials, use of coating techniques, and metal-nonmetal brazing for electrical, packaging and structural applications are reviewed, along with fluxless brazing, the use of glasses and glass ceramics for high temperature applications and nickel-based filler metals for components in contact with drinking water. With its distinguished editor and international team of expert contributors, Advances in brazing is a technical guide for any professionals requiring an understanding of brazing processes, and offers a deeper understanding of the subject to researchers and engineers within the field of joining. Reviews the advances of brazing processes in joining materials Discusses the fundamentals of brazing and considers specific materials, including super alloys, filler metals, ceramics and intermetallics Brazing of cutting materials and structural applications are also discussed

Book Description :

Although brazing is commonly regarded as a joining technique, the following chapter will introduce possibilities for using brazing as a coating technology, which offers new and unique solutions for applying functional coatings to surfaces. Details are presented of some fundamental aspects of this coating technology with regard to processes, metallurgical considerations and mechanical properties, followed by the various methods for producing coatings by brazing. Examples of applications are explained with regard to the various coating techniques. The chapter gives an overview of the major technologies of coating by brazing and demonstrates that this relatively unknown coating technique offers complementary possibilities to other well-established coating processes. It is shown that the specific possibilities of coating by brazing create a niche where this coating technique can offer superior solutions.

Book Description :

This contribution presents the state of the art in brazing metal–ceramic compounds. General problems during brazing of metal and ceramic and different process variations with appropriate brazing materials are described. The brazing process itself and interesting examination methods for metal–ceramic compounds are explained. For a selected material combination, the microstructure and strength behaviour are described. In the final section, recent results for induction brazing of metal–ceramic compounds are introduced as an energy-efficient alternative to conventional furnace brazing processes. The process-specific basics of induction brazing and furnace brazing, as well as the microstructure and strength behaviour for both processes, are compared.

Book Description :

The creation of a thermally induced metallic bond between aluminium components in the absence of powdered brazing fluxes has been achieved using a number of different techniques. Oxide disruption to promote the wetting and flow of filler metal on the surface is necessary for brazed joint formation. This can be achieved by making modifications to the brazing sheet surface, filler metal alloy and the use of composite alloy–flux materials. Different inert atmosphere brazing techniques and associated brazing mechanisms are described, including nickel brazing, filler metal alloying, electrochemical surface treatment and composite filler material developments.

Book Description :

The fundamental equations of wetting and adhesion are presented and the contact angles of non-reactive liquid metals and molten oxides on different types of solids are interpreted. The main features of reactive wetting are briefly described and illustrated. The two types of brazing used in practice (capillary brazing and sandwich brazing) are defined and the thermodynamics and kinetics of capillary infiltration are presented. The different configurations expected to occur in ‘sandwich brazing’ at varying intrinsic contact angles are described and illustrated. Three examples of brazing of metals and ceramics in non-reactive and reactive systems are discussed to show how wetting can affect brazability and the properties of brazed joints.

Book Description :

Compact aluminum heat exchangers are widely used in the automotive industry. The market in the heating, ventilation, air conditioning and refrigeration (HVAC&R) industry is expected to grow. Controlled atmosphere brazing (CAB) is the state-of-the-art mass production technology. This chapter presents the manufacturing process for compact aluminum heat exchangers (e.g. micro-channel heat exchangers) using CAB. Suitable aluminum alloys are introduced and the principles of brazing sheet metallurgy, filler metal selection and application are described. Fluoride fluxes and recent developments in flux modification and application methods are discussed, and wetting and flow behavior of molten aluminum filler metals during brazing are explored. Some phenomena due to filler/base metal interactions are included. Recent developments of CAB heat exchanger materials with enhanced corrosion resistance are reviewed, and corrosion testing methods are discussed.

Book Description :

This chapter investigates the problem of brazing heat-resistant materials – high nickel-base and γ-TiAl-base intermetallic alloys. Diffusion brazing with filler metals of the Ni–Cr–B and Ni–Cr–B–Si systems is inefficient for nickel alloys, while composite filler metals based on these systems yield satisfactory results. When used as an alternative to boron- and silicon-containing filler metals, alloys of the Ni–Cr–Zr systems do not form hard and brittle phases at the interface in the joints. Filler metals based on the Ti–Zr system are best suited for joining γ-TiAl-base intermetallic alloys. Ti–Zr–Fe and Ti–Zr–Mn alloys, which show promise as brazing filler metals are selected, and structures and mechanical properties of the brazed joints are presented.
