In this study, AlCrN coatings were deposited using modulated pulsed power magnetron sputtering (MPPMS) with different power pulse parameters by varying modulated pulsed power (MPP) charge voltages (350 to 550 V). The influence of power pulse parameters on the microstructure, mechanical properties and thermal stability of the coatings was investigated. The results indicated that all the AlCrN co...
Herein, we show that incorporation of ions during biomimetic coating deposition may be utilized to tailor the drug loading capacity of hydroxyapatite (HA) coatings. Pure biomimetic HA (HA-B) and Si-doped equivalents (SiHA-B) where deposited by a biomimetic process onto titanium dioxide covered titanium substrates. The antibiotic Cephalothin was incorporated into the coatings by adsorptive loadi...
نوآوری به عنوان یکی از مزیت های اصلی برای حیات شرکت ها محسوب می شود و همه ی سازمان ها برای بقا نیازمند ایده های نو و بدیع هستند. در تلاش برای رسیدن به نوآوری، اغلب سازمان ها بر پروژه های توسعه محصولات جدید از طریق تیم ها متکی هستند. امروزه، کار تیمی روشی پویا و پاسخگو برای دستیابی به پویایی مداوم محیط کسب و کار جهانی را فراهم می کند. تحقیقات در زمینه نوآوری بر اهمیت ایده سازی از طریق ترکیب، ادغ...
Silicon nitride (SiNx) coatings are promising for joint replacement applications due to their high wear resistance and biocompatibility. For such coatings, a higher nitrogen content, obtained through an increased nitrogen gas supply, has been found to be beneficial in terms of a decreased dissolution rate of the coatings. The substrate temperature has also been found to affect the composition a...
BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...
Abstract Liquid crystalline polymer (LCP) coatings offer avenues for the fabrication of devices with smart surfaces incorporating responsive topography, reflectivity, or polarization from their unique anisotropic optical and mechanical properties. LCPs have most commonly been made by photopolymerization reactive mesogens within confined cells. Here, an alternative method preparing LCP using ini...
Coatings that can self-modulate their optical properties as a function of an external stimulus are of significant technological interest. In this regard, the possibilities for thermoor electrochromic materials such as V02 and W03 are already comparatively well-known. Here, however, we explore a new kind of 'smart' coating, based on the active control of a plasmon resonance in nanoparticles. One...
Titanium dioxide-nickel oxide porous coatings were synthesized by Plasma Electrolytic Oxidation (PEO)/ ElectroPhoretic Deposition (EPD) in one step and within a short time. The main purpose of this research was to increase photocatalytic activity of titanium oxide by increasing surface area and coupling of titanium oxide with nickel oxide. Applied voltage effects on phase structure, surface mor...
Nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. Theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. The better mechanical properties can be obtained ...
AbstractSputtered MoS2 coatings have been mostly used as a solid lubricant. In this investigation, MoSx/Ni composite coatings with Ni contents varying from 0 to 22 % were deposited onto steel substrate using a DC magnetron sputter process. The MoS2/Ni ratio in the coatings was controlled by sputtering the composite targets. The composition, microstructure, and mechanical properties of the...
