Development of Ti–In alloys by powder metallurgy for application as dental biomaterial

Abstract Substantial progress has been made in Ti alloys’ properties and chemical composition. However, the effect of porosity indium content on biocompatibility corrosion behavior not sufficiently studied. Indium (In) is a promising nontoxic element that can replace other toxic elements, while associated with good biological response. The purpose this paper to evaluate achievability three Ti–In alloys 2.5, 5, 10 wt.% by powder metallurgy methods as dental prostheses. findings present work showed In acted grain refiner, allowed us obtain an 11.2-fold reduction for Ti–10In sample than Ti–2.5In alloy. total decreased according content, however, size greater mechanical comparison porosity, probably because low percentage. All values fell within ranges accepted literature implant applications. Ti3+ In3+ ion releases were below concentrations human body, maximum 0.43 0.016 ?g cm?2 h?1, respectively. Corrosion sensitivity addition due its surface protective Ti-matrix. These results proved utilizing methods, are feasible candidates prosthesis. Of prepared alloys, alloy it most appropriate be used implant.
