In this chapter, the underlying science of joining metal matrix composites (MMC) is described. Some specific examples of production of joining MMC produced by the authors are given to illustrate the key factors involved. A wide range of joining MMC is now available commercially. The properties of the MMC/metal ensembles can be related directly to the joining technique as well as the parameter and its effect in thermodynamics and mechanism involved, which must be controlled during joining processes. The choice of the best joint technique is related to the joining materials, final required properties, and the intended applications. The properties of the MMC/metal combinations depend on the joining interface of reaction zone produced during joining, which, in turn, depends on a joining route and subsequent thermal treatment. Some characteristics of diverse joining methods, as well a mechanic evaluations techniques to MMC joints, are analyzed. The effect of a reaction layer on the interface formed during joining of composites was studied. Additionally, some fundamental aspects and conditions to prepare ceramic-metal joints are analyzed. |
