Formation of MoS2/HA ceramic film on plasma electrolytic oxidized Ti-6Al-4V using mechanically synthesized method: Enhancing surface characteristics and biocompatibility for bio-implant
This study inspected the impact of mechanically synthesized molybdenum disulfide (MoS2) and hydroxyapatite (HA) coatings on plasma electrolytic oxidation (PEO) treated Ti-6Al-4V alloy. For the formation of MoS2-HA ceramic, varying compositions of MoS2 and HA (0, 3, 5, and 7 g) were mechanically synthesized (MS) for 6 h in a mechanical mixer containing PEO-treated Ti-6Al-4V alloy. The research aimed to evaluate the influence of these coatings on surface properties and bioactivity. The combined use of MoS2 and HA leverages the unique properties of both materials: HA provides excellent biocompatibility and corrosion resistance, while MoS2 enhances mechanical properties and scratch resistance. Surface characterization techniques, FESEM, XRD, and FTIR were employed to analyze the MS film's morphology, composition, and surface properties. Mechanical properties of ceramic were assessed through nanoindentation and scratch tester. PDP and EIS tests were conducted to evaluate the corrosion resistance of the ceramic. Moreover, the bioactivity of the ceramic was assessed through immersion tests in SBF, examining the formation and growth of apatite layers on the surface. EIS was also performed after SBF immersion. Results indicated that the MoS2-HA coatings significantly enhance the surface properties, corrosion resistance, and bioactivity of the PEO-treated Ti-6Al-4V alloy, with the optimal composition determined to be the sample of 3g MoS2 and 7g HA.
期刊介绍：
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
