Abstract
The Aluminium Oxide ceramic phase with its high hardness and strength, allied with the iron’s metallic phase, which it presents high ductility and high fracture toughness, make it a strong candidate to replace conventional materials such as WC-Co. The present work investigates the effect of high energy milling on the dispersion of Al2O3 and Fe phases. To achieve this goal, powders of Al2O3 and Fe in the proportion of 10% by mass of Fe were milled in the planetary mill Pulverisatte 7 of high energy. The powders were milled for 50 hours and they were collected at 5, 15, 30 and 50 hours. Throughout the work will be presented images of SEM, where greater homogenization between phases was observed, as well as the XRD to detect the present phases and to analyze the reduction of the sizes of the crystalline peaks.
