Investigation of PM parameters' effect on architecture of titanium foams using X-ray microtomography

Abstract

Titanium foams have been of interest in dental and orthopedic implants over the past few decades on account of their excellent mechanical properties, chemical stability, and biocompatibility. In this study, titanium foams with porosity ranging between 50 - 75% were produced by sintering at different temperatures via space holder method. Effect of sintering temperature was monitored. Changes in architectural features such as cell wall thickness distributions and cell wall porosity were investigated by the use of x-ray microtomography. Compressive strengths of the foams sintered at different temperature were also measured.
