“…There are coatings for enhanced wear and corrosion resistance by improving the surface hardness of the material that can be applied by different surface modifications techniques such as surface oxidation, physical deposition methods like ion implantation and plasma spray coatings, as well as thermo-chemical surface treatments such as nitriding, carburizing and boriding [43] [44].…”

“…The superb mechanical and tribological characteristics, high surface smoothness and high biocompatibility make DLC a material highly recommended for biotribological applications [3,[7][8][9][10][11][12]. DLC coatings deposited on metal elements prove extremely useful in implants, because of their high resistance to wear and other surface properties, such as low surface energy and chemical passivity, which prevent blood coagulation and promote adhesion of osteoblasts, especially in corrosive environments [13][14][15][16][17].…”

“…Since endoprostheses are vulnerable to various kinds of tribological and corrosive damage, their longterm reliability depends primarily on the materials used for the friction pair [5,7,9,18]. The main parts of an artificial joint are a UHMWPE cup and a metal or ceramic ball (head).…”

“…Metal heads are generally made of cobalt or titanium alloys because of their biocompatibility, and high resistance to corrosion and wear. CoCrMo alloys, which are also common, are characterized by relatively low friction resistance [7,8,10,18]. There are many surface engineering methods that can be used to modify the physical and chemical properties of artificial joints and extend their service life.…”

“…As attempts to improve the endoprosthesis design and material by significantly reducing wear has not been successful, investigations are being continued. Recent studies show that DLC coatings have the desired properties to be used as the surface of the endoprosthesis head and stem [3,5,7,10,12,17]. DLC coatings were discovered in 1971 by Aisenberg and Chabot, who obtained hydrogen-free amorphous carbon while cooling a low-energy carbon ion beam in argon [5,13,16,22,23].…”

This paper presents results of the structure analysis and tribological testing of a-C:H type diamond-like carbon (DLC) coatings deposited by Plasma Assisted Chemical Vapour Deposition (PACVD) on CoCrMo specimens. The DLC coatings were selected because of their good biocompatibility and high resistance to corrosion and wear. The surface structure and elemental composition were determined using scanning and transmission electron microscopy. The tribological tests of a cobalt-based alloy disk, or alternatively, a cobalt-based alloy disk with a diamond-like carbon coating, and an alumina ball were determined using a ball-on-disk tribometer under dry friction and lubricated friction conditions. Wear resistance was studied for a pin-on-plate tribological system: a polymeric pin made of ultra-high-molecular-weight polyethylene (UHMWPE) and a CoCrMo plate coated with DLC. The testing was conducted in lubricated friction conditions using Ringer's solution as a lubricant. The test results show that the application of DLC coatings definitely improves the service life of the surface. The DLC coatings were characterized by lower wear resistance and higher corrosion resistance than the CoCrMo alloy.K e y w o r d s : diamond-like carbon,

In 2010 there has again been an increase in the number of papers published involving piezoelectric acoustic sensors, or quartz crystal microbalances (QCM), when compared to the last period reviewed 2006-2009. The average number of QCM publications per annum was 124 in the period 2001-2005, 223 in the period 2006-9, and 273 in 2010. There are trends towards increasing use of QCM in the study of protein adsorption to surfaces (93% increase), homeostasis (67% increase), protein-protein interactions (40% increase), and carbohydrates (43% increase). New commercial systems have been released that are driving the uptake of the technology for characterisation of binding specificities, affinities, kinetics and conformational changes associated with a molecular recognition event. This article highlights theoretical and practical aspects of the principals that underpin acoustic analysis, then reviews exemplary papers in key application areas involving small molecular weight ligands, carbohydrates, proteins, nucleic acids, viruses, bacteria, cells, and membrane interfaces.
