Methodology for Obtaining Porous Metal Materials (Aluminum 6061) for Biomedical Applications Using Chips with Controlled Size
摘要
The porosity in materials used in medical applications for the replacement of bone tissues is a characteristic that seeks to be similar to the physical and mechanical properties of bone, this due to the functions that the bone performs by itself, such as: absorption, filtration and separation of fluids, damping of compressive loads, decrease in its density, etc. The reasons why it is important to propose and generate new methods to obtain porosity in materials planned for bone replacement, being this the objective of the present investigation, which is based on the generation of a method to produce porous metal materials, using the bases of a sintering process but with macro particles (chips) of aluminum 6061 as raw material. The final product reflects a random micro and macro interconnected porosity, while the density is reduced in some cases until more than 50%, this due to the lack of compression applied to the sintering process.
