Proper matrix-reinforcement bonding in cast metal matrix composites as a factor of their good quality

The mechanism by which the matrix connects the reinforcement (bonding of the composite structure) affects the quality of metal matrix composites. This article describes and documents the impact of metal matrix on various types of reinforcements of in situ and ex situ composites, by reviewing the relevant literature and making use of various analytic methods: optic microscopy, scanning electron microscopy and X-ray microanalysis. The reinforcement formation in the matrix of in situ composites has been described. The infiltration process of composite reinforcement has been discussed. The three basic composite classes have been presented. The reactivity of selected composite components has been pointed out.
