Wettability and corrosion tests of diamond films grown on Ti6Al4V alloy

Wettability of these films designed a small hydrophobicity that is very similar to those of other carbon structures used as biological implants. The surface energy value of 50.5 mJ m−2 indicated that is possible to get a good tissue adhesion on diamond films. These films were also exposed to various biological fluids, including isotonic NaCl and Ringer's solution for 1 month and acid-water solution for 2 months. Diamond surface chemical stability was analyzed from films micrographs by scanning electron microscopy (SEM). The results revealed that the diamond films surfaces were not degraded by environmental agents.
