Análisis espectroscópico y morfológico de una válvula artificial para el corazón.

Abstract

The materials that are in contact with the body system require the fundamental characteristic that allows their acceptance and integration in the organism, the biocompatibility. Likewise, they must show excellent mechanical, tribological and morphological properties, so that their provision of a service in the specific tissue is the most optimal, being able to sketch such characteristics through the characterization of these materials by spectroscopic and microscopic techniques. In this work, an artificial valve for the heart made of titanium and coated with diamond-like carbon (DLC), highly biocompatible material, was subjected to XPS, FTIR, and morphological analysis. A high interdiffusion of the coating and the substrate was found, together with a large signal of sp3 bonds. The CH3 terminal bonds represent a little compact film. The film roughness of the coating was low and adequate for hemocompatible purposes.
