Περιγραφή: A methodology has been developed for obtaining of porous castings from Al and aluminium A356 alloy. The methodology includes introduction of Ca into the melt for viscosity increasing and homogenization by mechanical stirring. This is followed by addition of TiH2, homogenization, subsequent formation of the porous structure and crystallization. A tomographic analysis of the porous samples was carried out and the main characteristics of their structure were determined. Tests were carried out on specimens of the castings involving abrasive wearing under dry friction conditions on a surface with hard-attached abrasive particles.
