abstract = "Titanium and titanium alloys are currently being used for clinical
biomedical applications due to their high strength, corrosion
resistance and elastic modulus. However, these materials have
recently been shown to exhibit ion release and poor physiological
integration that may result in fibrous encapsulation and further
biomaterial rejection. In order to be a successful replacement for
bone current approaches for enhancing the mechanical and
biological properties of Ti was alloyed Ti with Ta due to it
provides greatly improved mechanical properties which include
fracture toughness and workability. Studies have shown techniques
such ion beam etching, heat and alkaline treatment, SBF coatings
and anodization to promote altered cellular response on Ti and
Ti-alloys. In this study Ti-30Ta alloy was investigated ion beam
etching. The SEM was used to investigate the topography, EDS the
chemical composition, and surface energy was evaluate with contact
angle analyze due to the topography have effect on protein
adsorption, platelet adhesion, blood coagulation and bacterial
adhesion. This study concludes Ti-30Ta alloy substrate with ion
beam etching was not favorable for biomedical application.",
