Nanostructured Tantalum (Ta) thin films were deposited by plasma assisted chemical vapor deposition (PACVD) at duty cycles of 17%, 25%, and 33%. FESEM and MTT assay indicated that the Ta film deposited at duty cycle of 25% provides the best surface biocompatibility because of its flawless and uniform structure. Furthermore, Rockwell adhesion test indicated that the best film adhesion observed in Ta film that deposited at duty cycle of 25% and this attributed to its dominant α-phase structure.

Keywords: Nanostructure; Tantalum; PACVD; Biocompatibility
