Investigation Regarding Al-Al2O3 Composite Material Production and Its Weldability to Aluminum by Diffusion Welding
Abstract
In this study, firstly, a
composite material aluminum based and containing 10 % Al2O3
by weight is produced by powder metallurgy method. In the production of composite samples being 10 mm in diameter and
15 mm in length, first Al and Al2O3 powders were mixed
for 2 hours in a high – energy attritor
and then pressed in a unidirectional axial die at 800 MPa
pressure. The pressed samples were sintered in a tubular furnace in a
protective argon gas ambiance at 650°C for 2 hours. As for the second stage, the
composite samples have been welded by diffusion welding to an Al block material
in 99.5% purity and in the same dimensions at 5 MPa – constant load at
different temperatures and durations by diffusion welding. The strength values
of welded samples were determined by making shear tests from the welding zones
versus composite material.
