Advances in brazing

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.

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

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

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

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

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

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

Joining remains an enabling technology in several key areas related to the use of ceramics. Development of ceramic materials for electronic, biomedical, power generation, and many other fields continues at a rapid pace. Joining of ceramics is a critical issue in the integration of ceramic components in engineering design. This book includes reviews on the state-of-the-art in ceramic joining, new joining materials and methods, and modeling joint behavior and properties.
