Nano-mechanical and viscoelastic behavior of advance ultrafine graphite reinforced unsaturated polyester based prosthesis layup resin
Abstract: A new durable biomedical composite for prosthesis was designed to obtain enhance mechanical and viscoelastic properties, in particular nanohardness and young’s modulus. The nanoindentation technique was employed to investigate nano-scale mechanical properties of unsaturated polyester resin and its advance prosthesis lay-up nanocomposite resin with different amount of exfoliated graphite fillers loading. It has been observed that the young’s modulus of the nanocomposites gradually increase with increasing amount of reinforcement content. …

Nanostructured Cr-WS2 Solid Lubricant Coating for Space Applications
Abstract: Abstract Tungsten disulphide (WS2) is one of the widely used intrinsic low friction materials, which is commonly used in the form of coating. WS2 offers very low coefficient of friction only in non humid conditions. Presence of humidity destroys this property and restricts its utility. Modifying the structure of WS2 by adding certain metals helps in overcoming this limitation and in addition improves the mechanical properties. Further, deposition technique and …

Characterization Techniques for Thin Film Coatings Based on SiO₂, TiO₂, and ZrO₂
Abstract: Thin film coatings made from silicon dioxide (SiO₂), titanium dioxide (TiO₂) and zirconium dioxide (ZrO₂) have attracted great interest owing to their excellent optical, electrical, mechanical and chemical properties. These oxide thin films are widely used in microelectronics, solar cells, sensors, biomedical devices, photocatalysis, anti-reflective coatings and protective layers. The structural, morphological, compositional, optical and mechanical properties of these coatings are closely related to their performance and reliability. Therefore, thorough …

Development of Multilayer Metallic Coatings with Graded Interfaces for Enhanced Wear and Fatigue Resistance in Aerospace Components
Abstract: This study presents a comprehensive investigation into the development and characterization of multilayer metallic coating systems with compositionally graded interfaces, specifically engineered to enhance wear and fatigue resistance in aerospace structural and rotating components. Four coating architectures were systematically designed: (i) CrN/TiAlN bilayer, (ii) TiN/TiAlN/TiAlSiN gradient trilayer, (iii) CrAlN/AlCrN nanolaminate, and (iv) a novel five-layer CrN–TiN–TiAlN–AlCrN–TiAlSiN functionally graded system (FGS). Coatings were deposited via high-power impulse magnetron sputtering (HiPIMS) and …
