“…Industrial research is focusing on TiSiCN coatings for their versatility in both processing and use, addressing diverse demanding applications, as recent work suggests, such as high speed machining in dry or near-dry conditions [4] coating of piston rings [11], and of prosthesis components [12]. The availability of different processes for the deposition of TiSiCN coatings -namely Chemical Vapor Deposition, CVD [6][7], Plasma Enhanced (PE) CVD [5][6][7][8], sputtering [13] and plasma enhanced sputtering arc ion plating [14] has been influential to its industrial implementation by enabling processing in a wide range of conditions and tailoring of material properties. The microstructure of this coating -formed through selforganization as a result of spinodal transformation-consists of an amorphous matrix of silicon nitride or silicon carbonitride with a dispersion of TiCN nanocrystals [4,7,9].…”

In this study, TiSiCN coatings, with and without a Ti/TiN/TiCN interlayer, are deposited on tempered and plasma-nitrided H13 hot-working tool steel substrate by pulsed direct current plasma enhanced chemical vapor deposition. The self-lubricant super hard TiSiCN coatings have a nanocomposite structure consisting of an amorphous SiCN matrix embedding TiCN nanocrystals. In the presence of the graded interlayer, coating adhesion improves significantly, as revealed by a 40% increase of the critical load for adhesion failure in scratch testing of the coated samples. The formation of shorter radial cracks around the indentation zone during Rockwell C indentation test reveals that the coating with the graded interlayer has a higher toughness compared to the single layer coating. The wear rate of the graded coating is found to be about three times lower than that of the single layer coating, which can

“…TiN, TiC, TiC x N 1− x , and even DLC films have been frequently used. TiN, TiC, TiSiN, and TiCN can be synthesized using the volatile TiCl 4 precursor and the reactant gases of N 2 , H 2 , SiH 4 , CH 4 , etc., at a high temperature . Such Ti‐based films exhibit extremely high hardness (up to 100 GPa) and wear resistance compared with Ti substrate.…”

Thanks to a considerable number of fascinating properties, titanium (Ti) and Ti alloys play important roles in a variety of industrial sectors. However, Ti and Ti alloys could not satisfy all industrial requirements; the degradation of Ti and Ti alloys always commences on their surfaces in service, which declines the performances of Ti workpieces. Therefore, with aim to further improve their mechanical, corrosion and biological properties, surface modification is often required for Ti and Ti alloys. This article reviews the technologies and recent developments of surface-modification methods with respect to Ti and Ti alloys, including mechanical, physical, chemical, and biochemical technologies. Conventional methods have limited improvement in the properties and/or restriction on the geometry of workpieces. Therefore, many advanced surfacemodification technologies have emerged in recent decades. New methods make Ti and Ti alloys have better performance and extended applications. With requirement of high surface properties in future. Understanding the mechanism in various surface-modification methods, combining the advantages of current technologies and developing new coating materials with high performance are required urgently. As such, incorporation of different surface-modification technologies with high-performance modified layers may be the mainstream of surface modifications for Ti and Ti alloys. . His current research interests focus on the metal additive manufacturing (e.g., selective laser melting, electron beam melting), titanium alloys and composites, and processing-microstructureproperties in high-performance materials.

“…Decreased bacterial colonization on TiO 2 coatings is observed even though these surfaces promote osteoblast adhesion and differentiation [14]. Various surface modification methods such as plasma electrolytic oxidation (PEO) [16], chemical vapor deposition (CVD) [17], thermal annealing [18], and sol-gel [19] have been applied to prevent biofilm formation on the Ti implants surfaces. It has also been shown that bacterial adhesion is influenced by the topography and roughness of the TiO 2 coating present on the implant surface.…”

Topography and surface chemistry can significantly affect biofilm formation on dental implants. Recently, the γ-TiAl alloy was considered as the most reliable candidates for the preparation of dental implants because of its excellent mechanical strength, chemical stability and biocompatibility. The emphasis of this study lies in the effects of high-speed milling assisted the minimum quantity of lubrication (HSM-MQL), micro-current wire electrical discharge machining (mWEDM), Er,Cr:YSGG laser and sandblasting/largegrit/acid-etching (SLA) treatments on surface morphology, topography, chemical composition, wettability and biofilm-associated infections on the surface of each group. The surface-treated samples were analyzed using a scanning electron microscope (SEM), SEM surface reconstruction, energy dispersive x-ray spectroscopy (EDS) and water contact angle measuring system. SEM and topography images of mWEDM and laser-treated surfaces showed more irregular surfaces compared to SLA and HSM-MQL surfaces. Results showed that mWEDM and laser-treated surfaces revealed hydrophobic behavior. A significant decrease of biofilm formation was observed on mWEDM treated surface due to the hydrophobicity and existence of the copper element in the recast layer chemical composition. Moreover, EDS confirmed that the zirconium, silicon, and fluorine elements were decorated onto the SLA treated γ-TiAl surface that can have a direct effect on the anti-bacterial activity.
