Análisis de material sinterizado aluminio 1060 con BABBIT B 23 ALLOY 2 y su incidencia en la resistencia a la tracción, dureza y desgaste combinados por mezcla de polvos

Abstract

The metallic powders of the materials Aluminum 1060 and Babbit b 23 alloy 2 were obtained by means of the mechanical milling process in a ball mill, which took a duration of 9 hours, optimizing that the area is free of contaminating agents, to achieve the purity of the materials and the combination of aluminum with babbit methods. These groups were mixed in a percentage of 10%, 20%, 30% of Babbit and the rest with aluminum, from which it obtained three different groups of volumetric fractions to be studied; The compaction of the volumetric fractions corresponds to a group that was prepared for the cold pressing method with a pressure of 270 MPa which in the sintering process reached a temperature of 660 ° C. In the present investigation, the influence of the changes of percentages in Babbit in the mixture with the Aluminum, likewise it is studied in the mechanical properties that to the durability, wear and traction exposing the samples to tests under the ASTM norms. These tests reflect that the combination of these materials in a volumetric fraction of 80% aluminum 1060 with 20% Babbit b 23 alloy 2, greatly improve the resistance and wear resistance in both cases, and in the case of the Babbit better the tensile strength. 10% and 30% of babbit deteriorate the mechanical properties of the combination of the materials obtained by the powder metallurgy method
