What Is Diffusion Bonding

Diffusion Bonding as a Production Process

Diffusion Bonding of Materials

Diffusion Beading of Materials is an attempt to pool the experience in vacuum diffusion bonding accumulated by a number of mechanical engineering works, research establishments, and colleges. The book discusses the principal bonding variables and recommended procedures for diffusion bonding in vacuum; the equipment for diffusion bonding and production rate; and the mechanization and automation of equipment. The text also describes the diffusion bonding of steels; the bonding of cast iron and cast iron to steel; and the bonding of dissimilar metals and alloys. The bonding of refractory and active metals and their alloys; the bonding of high-temperature alloys, nickel and nickel alloys; and the bonding of cemented carbides and of a cemented carbide to steel are also considered. The book further tackles the repair and reconditioning by diffusion bonding; the bonding of porous materials; and diffusion metallurgy. The text also encompasses nonmetals and their joining to metals; quality control of diffusion-bonded joints; accident prevention; and cleanliness in vacuum diffusion bonding.

Diffusion Bonding 2

There is currently great interest in the process of diffusion bonding. The main thrust has been in the joining of advanced materials such as superplastic alloys, metal matrix composites and ceramics and, most importantly, to introduce the process into mass-production operations. Diffusion bonding has also led to reduced manufacturing costs and weight savings in conventional materials and developments in hot isostatic pressing have allowed greater design flexibility. Since the first conference on Diffusion Bonding, held at Cranfield in 1987, considerable advances have been made and it was therefore considered appropriate to organise the Second International Conference on Diffusion Bonding which was held at Cranfield Institute of Technology on 28 and 29 March 1990. The meeting provided a forum for the presentation and discussion of recent developments in Diffusion Bonding and was divided into four main subject areas: steel bonding and quality control, diffusion bonding of aluminium alloys, bonding of high temperature materials and general applications. This structure is retained in the proceedings. DAVID STEPHENSON vii CONTENTS v Preface ......................... .
