Preliminary Tests for Ti-Mo-Zr-Ta Alloys as Potential Biomaterials

Abstract

Nowadays, there is a continuing concern for the research and development of alloys for medical and biomedical applications. In order to check the biocompatible character of a new Ti-Mo-Zr-Ta alloys, it is necessary to carry out preliminary laboratory tests to follow how a biomaterial surface would interact with the host. The paper presents tests for Ti-Mo-Zr-Ta alloys like contact angle and DSC test to identify biocompatible character. Contact angle measurement is an experimental technique used to assess the hydrophilic or hydrophobic character of surfaces by reference to the 90° contact angle value and to characterize the thermal behavior, for temperature range between 36.5-37.2°C, interval which a biomaterial works inside the healthy human body, was used DSC test.
