Abstract

High-energy ball milling, hot pressing and plasma immersion ion implantation are important techniques for improving surface properties of several materials nowadays. They are studied to enhance their efficiency and subsequently enlarge the range of their applicability. Ti-Si-B alloys present potential for high temperature utilization, although their unique properties have not been explored to their full extent yet. After characterization and evaluation of some physicochemical aspects of commercial alloys (SS304, Al-7075 and Ti-6Al-4V) and Ti-Si-B powder alloys treated by PIII, other important features of these alloys and characterization methods remain to be explored. Chemical composition, hardness, density, phase and particle morphologies, corrosion and wear resistance, and tensile strength; those can be cited as objects of study which continue to deserve attention from researchers within the materials engineering universe, as well as from other correlated sciences. In order to broaden the range of knowledge gathered concerning the postulated alloys, the present work is intended to be performed with the support of the Leibniz Institute of Surface Modification in Leipzig, Germany. Under the supervision of Prof. Stephan Mändl, further research into physical and mechanical surface properties shall be undertaken, including but not limited to: (i) secondary ion mass spectroscopy; (ii) nanohardness measurements; (iii) fatigue tests; and (iv) wear tests.
