Achieving fast and strong adhesion to jawbone is essential for dental implants. Thin deposited films may improve osseointegration, but they are prone to cohesive and adhesive fracture due to high stresses while screwing the implant into the bone, leading to bared, less osteoconductive substrate surfaces and nano-and micro-particles in the bone. Aim of this work is the investigation of the cohesion and adhesion failure stresses of osteoconductive tantalum, titanium, silicon, zirconium and aluminium oxide and diamond-like carbon films. The tribological behaviour under dry and lubricated conditions (Ringer solution) reveals best results for diamond-like carbon, while cohesion and adhesion of zirconium oxide films is highest.Keywords: biotribology, thin films, lubricationOsiągnięcie szybkiego i trwałego przylegania powierzchni biomateriału do kości szczęki ma zasadnicze znaczenie dla implantów dentystycznych. Cienkie osadzone filmy mogą poprawić osteointegrację ale są podatne na kohezyjne i adhezyjne pękanie podczas wkręcania implantu do kości, prowadząc do odsłoniecia mniej osteokonduktywnych powierzchni podłoża oraz powodując tworzenie się nano-i mikro cząstek. Celem niniejszej pracy są badania naprężeń wywołujących defekty w osteointegracyjnych filmach na bazie tantalu, tytanu, cyrkonu oraz tlenku aluminium i diamentopodobnych. Tribologiczne najlepsze właściwości w warunkach suchych i smarowania (roztwór Ringera) wykazały powłoki diamentopodobne, natomiast spójność i przyczepność filmy z tlenku cyrkonu.

“…Numerous studies on Si-based ceramics have shown that the chemical reaction resultant such as SiO 2 or SiO x would be formed on the friction contact surface as in reactions [1] and [2] (Suh,et al (25); Fischer and Mullins (26)). It was consequently proposed that the further tribochemical products of colloidal silica in water would function as a good boundary lubricant between the contact faces (reaction [3]; Xue and Kato (27); Kato and Adachi (28)). The severe wear of the SiO 2 counterpart indicated easy formation of colloidal silica between the GLC film and SiO 2 , resulting in the greatest decrease in FC for the GLC-SiO 2 tribopair in water.…”

The tribological performance of graphite-like carbon (GLC) films coupled with different ceramics including Si 3 N 4 , SiC, WC, Al 2 O 3 , ZrO 2 , and SiO 2 were comparatively studied in ambient air and water. The results showed that the GLC films could exhibit low friction and wear with small differences when sliding against engineering ceramics in both environments. Water played a different role in the tribological performance of GLC films, which was closely related to the nature and wear behavior of the coupled ceramics. Accordingly, three conditions of friction coefficient (FC) and wear rate (WR) of GLC films sliding against different ceramics in water compared to those in ambient air were found: similar FC with lower WR, lower FC with lower WR, and lower FC with higher WR. The SiO 2 counterpart resulted in high friction and wear of GLC film in ambient air, but it only slightly affected the tribological performance of GLC film in water. The GLC film coupled to Si 3 N 4 ceramic exhibited optimum tribological performance in both ambient air and water.

“…Not only does this film possess high chemical stability, a low friction coefficient, and excellent anti-wear properties [8,9], but it also exhibits better anti-wear properties in water than in the atmosphere [10], thereby providing the possibility of compensating for the poor tribological performance of titanium alloys in an aqueous environment. However, because of the low hardness of titanium alloys, it has not been possible to coat them directly with hard GLC films.…”

A duplex treatment involving nitrogen ion preimplantation and gradient interfacial transition was performed to obtain a high-performance graphite-like carbon (GLC) coating on a Ti6Al4V alloy. Characteristics of the as-deposited coating systems were systemically investigated by Raman spectrometry, scanning electron microscopy, atomic force microscopy, nano-indentation, and scratch tests. The friction and wear behaviors in distilled water and sea water environments were evaluated by a ballon-disk tribometer. The results showed that the GLC multilayer coating on nitrogen ion-implanted Ti6Al4V possessed a greater hardness and adhesion strength than to that on un-implanted Ti6Al4V. The tribological performances of these duplex process systems showed a great improvement in both the distilled water and sea water environments. In particular, the Cr/CrN/GLC coatings on nitrogen ion-implanted substrates demonstrated the best friction and wear behaviors. These striking improvements were attributed to the greatly enhanced interface strength between substrate and coating by the nitrogen ion implantation process and improved adhesion strength between gradient layers by the appropriate gradient interlayers with a similar thermal expansion coefficient.
