Process for obtaining synthetic foam with aluminum matrix Al-5052 by method of tixoinfiltration

Abstract

The metallic foams have lower density, and important physical, mechanical, thermal and acoustic properties, has been highlighted in its use in innovative technologies. As a subgroup of the class of metallic foams, the syntactic metallic foams which consists of the addition of hollow ceramic balloons in a metallic matrix in aluminum Al-5052 by process of tixoinfiltration. The microstructure was studied by optical and electron microscopy extended by energy-dispersive X-ray spectrometry, while the basic mechanical properties were mapped by standardized compression tests. Therefore, a syntactic foam design was developed in this work, where we obtained a 30% reduction in density and a reasonable increase in hardness due to the homogeneous dispersion of the ceramic balloons
