The aim of this work is the study of sintered titanium parts for medical applications components, via process of Powder Metallurgy (M/P). This study will be a basis for the manufacture of an orthodontic interpenetrating screw. A study of constituent powders was accomplished and samples were prepared. In sequence, its physical properties were analyzed. For all alloy composition studied, the parameters of production process were respected as: compactation pressure, sintering atmosphere, and sintering time. The porosity determined by Archimedes principle was approximately 11.5%. This result is comparable to that found in the literature. The average density obtained by M/P was 4.03 g/cm3 for sintered titanium, with a density close to theoretical density of titanium, 4.5 g/cm3.
Key words: powder metallurgy, sintering, orthodontic screw.Downloads
