“…Some of them display the most excellent properties of biocompatibility, chemical inertia and thromboresistance that any other bioceramics. Another advantage of these materials is that their physical characteristics are close to those of the bone [42]. Thus, their densities, according to the type carbon, change between 1.5 -2.2 g/cm 3 , and their elastic modules between 4 -35 GPa.…”

A strong interest in the use of ceramics for biomedical engineering applications developed in the late 1960´s. Used initially as alternatives to metallic materials in order to increase the biocompatibility of implants, bioceramics have become a diverse class of biomaterials, presently including three basic types: relatively bioinert ceramics; bioactive or surface reactive bioceramics and bioresorbable ceramics. This review will only refer to bioceramics "sensus stricto", it is to say, those ceramic materials constituted for nonmetallic inorganic compounds, crystallines and consolidated by thermal treatments of powders to high temperatures. Leaving bioglasses, glass-ceramics and biocements apart, since, although all of them are obtained by thermal treatments to high temperatures, the first are amorphous, the second are obtained by desvitrification of a glass and in them vitreous phase normally prevails on the crystalline phases and the third are consolidated by means of a hydraulic or chemical reaction to room temperature. A review of the composition, physiochemical properties and biological behaviour of the principal types of crystalline bioceramics is given, based on the literature data and on the own experience of the authors. Key words: alumina, zirconia, zirconia-toughened alumina, graphite, hydroxyapatite, bioactive silicates, bioeutectic � , tricalcium phosphate Materiales biocerámicos cristalinosA finales de los años sesenta se despertó un gran interés por el uso de los materiales cerámicos para aplicaciones biomédicas. Inicialmente utilizados como una alternativa a los materiales metálicos, con el propósito de incrementar la biocompatibilidad de los implantes, las biocerámicas se han convertido en una clase diversa de biomateriales, incluyendo actualmente tres tipos: cerámicas cuasi inertes; cerámicas bioactivas o reactivas superficialmente y cerámicas reabsorbibles o biodegradables. En la presente revisión se hace referencia a las biocerámicas en sentido estricto, es decir, a aquellos materiales constitutitos por compuestos inorgánicos no metálicos, cristalinos y consolidados mediante tratamientos térmicos a altas temperaturas. Dejando aparte los biovidrios, los vitrocerámicos y los biocementos, puesto que, si bien todos ellos son obtenidos por tratamiento térmicos a altas temperaturas, los primeros son amorfos, los segundos son obtenidos por desvitrificación de un vidrio, prevaleciendo normalmente la fase vítrea sobre las fases cristalinas, y los terceros son consolidados mediante una reacción química o hidráulica a temperatura ambiente. Así pues, teniendo en cuenta la abundante bibliografía sobre el tema y la experiencia propia de los autores, se presenta una revisión de la composición, propiedades fisicoquímicas, aplicaciones y comportamiento biológico de los principales tipos de biocerámicas cristalinas.

Diamond-like carbon (DLC) and amorphous carbon (a-C, a-C:H) coatings, respectively, have been proposed since many years as potential materials for biomedical applications due to their chemical inertness, low friction coefficient, high wear resistance, bio-and haemocompatibility. [1][2][3][4][5][6] The feasibility of amorphous carbon coatings was investigated for a variety of applications like surgical needles, [2] orthopaedic implants and prostheses, [7][8][9][10][11] medical guidewires, [12][13][14][15] coronary artery stents [16,17] and also for mechanical heart valve replacement and other solid implants. [18][19][20][21][22][23] The functionality, performance and durability of artificial surfaces in vivo are determined and often limited by their interaction with blood or tissue. However, the coagulation mechanism of blood on amorphous carbon (DLC) films in such a biomedical environment is not understood in detail even if the biocompatibility of DLC coatings was described early by many reports. [1,3,[24][25][26] Extensive information on individual aspects, like protein adsorption, platelet adhesion and activation on carbonaceous surfaces has been accumulated in the literature. [27][28][29] Since a few years more sophisticated approaches to the scientific understanding of the complex interaction of blood and inorganic surfaces are emerging by addressing this field through fundamental and interdisciplinary research efforts offering synoptical views based on materials science, chemistry, biology, physics, physical chemistry and medicine. [30][31][32] Main factors have been recognised to influence significantly the cell adhesion and interaction on amorphous carbon: these include the constitution of the carbon films and the fraction of the sp 3 bonds, [12,30] the surface energy and hydrophobicity, [27] and the surface roughness and topography. [26,31] The properties of a-C and DLC coatings, especially the biofunctional ones, can further be modified by incorporating other elements in the coatings, such as H, N, F, P, Si and metals. [4,5,[33][34][35][36][37][38][39] It is well known that the incorporation of additional elements into an amorphous carbon matrix has a very strong impact on the surface energy and wettability of such coatings. [40][41][42] Combining various surface modification methods should thus offer new tools for a future engineering design of biofunctional thin film materials, covering a wide range of properties, for example from strongly hydrophilic to extremely hydrophobic. Recently, it was shown that the modification of the inherent surface topography of carbon films on the nano-scale by proper adjusting of the deposition process and kinetics can strongly impact the wetting behaviour. [43] Similar or complementary effects were achieved through creating an artificial micro-or nano-scale surface topography by laser-patterning or plasma-etching or by subsequent thermal processing of carbon coatings. [44][45][46] From the biological perspective, the competitive adsorption of several plasma proteins (al...

“…Guseva et al [2] showed that on the bore of carbynes, a new material ''carbylan'' can be obtained and used for medical implants. It seems that Thomson et al [3], Lettington et al [4,5], Mitura et al [6,7] and, McLaughlin et al [8] have proposed the carbonaceous materials most suitable for medicine DLC, and amorphous and nanocrystalline diamond that have perfect mechanical properties [9]. The tests, that have been done till now, have confirmed that especially the implant covered with nanocrystalline diamond fulfils the demands for biomaterials.…”

The NiTi-and Cu-based shape memory alloys (SMAs) constitute two groups of functional materials for which medical and industrial applications have been developed in the last two decades. This is due to their unique properties i.e., one-and two-way shape memory and pseudoelasticity effects. Especially NiTi alloys found wide application in medicine.In vitro studies on NiTi showed the dependence of the alloy biocompatibility and corrosion behaviour on surface treatment. There also appeared reports of cases of patients sensitive to this material, in which allergic reactions to nickel in NiTi implants or orthodontic wires are shown.The development of carbon, ductile coatings for SMAs with the aim of improving the alloy biocompatibility, wear and corrosion resistance is the subject of the paper. This work reports on the manufacturing of SMA, synthesis of carbon coating onto SMA and presents first results of surface characterisation.KEY WORDS: shape memory alloys, carbon coatings, plasma activated chemical vapour deposition.
