“…The important properties of any such carbon films are mapped by the methods used for deposition, sp 3 /sp 2 ratio, % of hydrogen, disorderliness in the films, etc. With the superior properties of carbon films (having high sp 3 percentage) such as micro-hardness like sapphire, low frictional coefficient, inertness to any aggressive chemical and also ability to coat geometrically complex bodies; these carbon films can be used in the applications like antisticking overcoats for computer disks [8], anticorrosive coating for surgical instruments [9], solar cells [10,11], electron field emission [12,13] and electrodes in electrochemical reactions [14], etc. It is worthwhile to mention that the nature and properties of carbon films play an important role in various applications.…”

“…6,7 The deposition of DLC, on a wide range of substrate materials, has received considerable attention in the literature. Favorable results have been reported for applications such as surgical needles for corneal surgery, 8 materials for total joint replacement, 3,9 orthopedic pins and screws, 10 dental prostheses, 11 medical guidewires, 12 heart valve replacements, 13 and rotary pumps for left ventricular assistance. 14 The use of TiN for dental prostheses [15][16][17][18] and for hip joint and heart valve replacements 19,20 has also been reported.…”

The hemocompatibility of a TiN/TiC/diamond-like carbon (DLC) multilayer structure, deposited on titanium substrates for use as coatings for a heart valve prosthesis, has been studied through the adsorption of blood proteins and the adhesion and attachment of blood platelets. All of the surfaces were characterized by stylus profilometry and water contact angles. The adsorption of albumin and fibrinogen to the surfaces was assessed using the Amido Black assay, whereas platelet attachment was studied by scanning electron microscopy and quantified using stereological techniques. The degree of platelet spreading on the surfaces was seen to correlate with differences in surface energy, indicated from contact angle measurements. The greatest spreading was seen on the more hydrophilic surfaces. When studying protein adsorption to the surfaces, no correlation could be determined between contact angle results and levels of adsorption, although the most hydrophilic surfaces did appear to promote greater amounts of fibrinogen adsorption. Thrombus formation was observed to some degree on all of the surfaces, with the exception of the DLC coating. This coating also promoted less spreading of platelets than the other surfaces. The good hemocompatibility of the DLC coating is attributed to its hydrophobicity and smooth surface, resulting in a higher ratio of albumin to fibrinogen than any of the other surfaces.

“…Although no universally accepted nomenclature has been agreed upon, amorphous carbon with some component of sp 3 -hybridized atoms is commonly referred to as diamondlike carbon (DLC). [35][36][37][38][39] These materials possess atomic number densities greater than 3.19 g atom/cm 3 , and may possess densities closer to that of diamond (3.51 g/cm 3 ) than that of graphite (2.26 g/cm 3 ). Diamondlike carbon has been considered for use as a coating for prosthetic joint materials because it possesses hardness, low friction, wear resistance, corrosion resistance, and immunity to scratching by third body wear particles.…”

Surface Modifi cation in Bioapplications OverviewFunctionally gradient materials are characterized by uniform changes in composition, crystallinity, and/or grain structure, which may provide unique biological, chemical, or mechanical functionalities in next-generation medical devices. In this article, the development of functionally gradient Zr-Nb alloys, hydroxyapatite coatings, and diamondlike carbon-metal coatings for medical applications is reviewed.
