“…Последние достижения в области осаждения и характеристики DLC-пленок облегчают производство материалов с контролируемыми свойствами, разрабатываемых с учетом конкретных требований. В некоторых случаях после осаждения пленки могут быть дополнительно модифицированы (например, газоплазменная обработка или лазерное облучение) для улучшения некоторых характеристик и получения желаемых свойств [11].…”

“…In addition, the materials required for the manufacture of the implants must be biologically safe, non-carcinogenic, non-toxic to the human body, inhibiting the formation of organic biofilms and bacterial growth [2][3][4][5][6]. For these reasons, the implants are made from corrosion-resistant materials with high biocompatibility: metals (titanium, stainless steel), metal alloys (titanium-aluminum-vanadium, cobalt-chromiummolybdenum alloys), ceramics (usually aluminum, zirconium and titanium compounds) or polymeric materials [2,3]. Mechanical wear of the implant due to corrosion and friction over time causes the undesirable phenomenon of metallosis: metal ions, atoms and molecules, as well as small fragments of implant wear can penetrate into soft biological tissues and spread throughout the body.…”

“…This can cause cytotoxicity, allergic or implant rejection reactions, painful inflammation or infection of the surrounding tissues, and can lead to the development of tumors and cancer cells. The risk of implant relaxation, fracture, disintegration, and premature wear also remains relevant [2,3,[6][7][8]. As a result, the non-metallotic polymeric implants have been increasingly used in recent years.…”

The aim of this experimental work is to identify how the surfaces of materials that are most often used in medical implants and prostheses, affect the properties of the deposited amorphous carbon films. The DLC films were formed on the stainless steel, aluminium, polyetheretherketone (PEEK) and polycaprolactone (PCL) surfaces by PECVD method using C 2 H 2 gas plasma and their properties was compared with the films deposited on silicon. The differences of the films properties were determined by a null-ellipsometry and Raman spectroscopy. It was found that the thicknesses of the carbon coatings deposited on metallic substrates are larger than on the silicon when the deposition conditions were the same. When the films are formed at high bias voltage the refractive index of the DLC films deposited on stainless steel are lower compared to the coatings on silicon but the extinction coefficients are higher. Raman spectra shows that sp 2 bonds concentration is higher in this case. When the ion energy is lowest (bias voltage -400 V), Raman spectroscopy shows that D peak isn't observed on the Si-deposited carbon coating, while the typical carbon amorphous coating is formed on the Al substrate. The thickness of amorphous carbon coatings deposited on the polymers depends on the bias voltage, and the optical properties depend on the type of polymer. The coatings deposited on PCL have a much higher refractive index than on PEEK.

The wear of ultrahigh-molecular weight polyethylene (UHMWPE) tibial inserts in total knee arthroplasty (TKA) remains a major limitation that hinders the longevity of clinically successful devices. Surface properties significantly affect the overall performance of TKA, and surface modification with mechanically and chemically stable materials is an effective method for overcoming the wear of TKA. However, wear tests are not cost-efficient or time-efficient; thus, the effects of geometric, loading, and alignment perturbations are often evaluated via parametric studies. Computational wear prediction using a finite element (FE) model followed by validation through comparison with experimental data is effective for assessing new prosthetic designs or surface change methods prior to functional testing and surgical implementation. The aim of this study was to evaluate the weight loss, wear depth, and kinematics for different surface properties, including nanostructured diamond (NSD), diamond-like carbon (DLC), titanium-nitride (TiN), and oxidized zirconium (OxZr) on femoral components in TKA using FE analysis under gait-cycle loading conditions. Weight loss and wear depth were lowest with OxZr followed by TiN, NSD, and DLC. However, the DLC femoral component did not show any improvement in wear rate compared to an uncoated cobalt-chromium (Co-Cr) femoral component. Not all surface changes applied in this study did lead to improvement in wear performance. However, this study demonstrates the potential of OxZr and TiN for reducing UHMWPE wear and offers new insights into the effects of wear on TKA.
