Abstract
Powder metallurgy is a complex technology that allows obtaining various alloys with special properties which successfully replace alloys achieved by classical technologies. The ability to easily modify classic chemical compositions makes this technology an instrument in the hands of researchers that enables them to always improve the properties of sintered alloys. In addition, the technology itself is very permissive, and new technical solutions can always be found in the technological process of pieces manufacturing. Among the materials very used in the technique, which is very well suited to this technology is titanium. Titanium in combination with other chemical elements greatly improves its operating behavior of obtained material. Therefore, this study proposes a combination of titanium with tin and graphite, recommended for improving wear resistance. The other elements used in the mixture, Al, Zr, Mn help to improve the mechanical properties. The paper intends to present a study on the wear resistance of this Ti alloy, sintered in different ways. SEM and spectrometry analyzes for sintered parts are also presented.
