dc.descriptionLos materiales que están en contacto con el sistema corporal requieren de la característica primordial que les permita su aceptación e integración en el organismo: la biocompatibilidad. De igual manera, deben exhibir excelentes propiedades mecánicas, tribológicas y topográficas para que su prestación del servicio en el tejido especificado sea el más óptimo, pudiendo esbozar estas características mediante la caracterización de estos materiales a través de técnicas espectroscópicas y microscópicas. En el presente trabajo, una válvula artificial para el corazón fabricada en titanio y recubierta con diamond-like carbon (DLC), material altamente biocompatible, fue sometida a análisis XPS, FTIR y morfológico. En estos se encontró una alta interdifusión del recubrimiento con el sustrato junto con una gran señal de enlaces sp3 . Los enlaces terminales CH3 suponen una película poco compacta. La rugosidad del recubrimiento fue baja y adecuada para fines hemocompatibles.
dc.descriptionThe 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.
