Study of two powder metallurgical methods used in composed biomaterials manufacturing of titanium and hydroxyapatite

Abstract

The following work presents a comparative analysis between two manufacturing methodologies that use powder metallurgical methods, that allow obtaining titanium-based sintered parts with the addition of hydroxyapatite as a bioactive material. The first method uses traditional techniques for obtaining samples by powders compaction through presses and metal molds. The second method employs the gel-casting technique combined with 3D printing technology for mold making. An analysis of the manufacturing methods, the technology used in the development of molds, the sintering variables and the mechanical properties about titanium and hydroxyapatite´s samples is carried. Some of the mechanical properties that will be analyzed are the modulus of elasticity, mechanical resistance, yield
point, elongation and hardness.
