The effecTs of Niobium oN The bioacTiviTy of Ni-Ti-al-Nb shape memory alloys This work aims to analyze the effects of niobium on the bioactivity of a titanium, nickel, aluminum, and niobium alloy obtained by the Plasma Skull Push Pull process (PSPP). Titanium alloys, such as NiTinol (NiTi), are metallic biomaterials that have wide application in health and surgical prostheses. in this work the microstructural and bioactivity characteristics of the alloys are evaluated. The addition of aluminum improves alloy ductility and reduces its cost. The addition of niobium favors the hydroxyapatite nucleation. Therefore, the addition of the combination of the two elements contributes to lower cost and better alloy bioactivity.
The purpose of this work is to describe the research proposal of use of cladding to produce an AISI type 1020 and titanium steel sandwich structure. This work was presented at the VI GPESE Workshop of the Exhaust Systems Research Group of the Federal University of Itajubá. A brief review was used to investigate the main components of the cladding process in the literature to obtain a sandwich-type composite (clad). It is expected that the properties of the sheet steel combined with the titanium powder, generate a material having a long cutting strand where the titanium is placed, and the surfaces both lower and upper, have good impact strength.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
