Effect of cenosphere fillers on mechanical strength and abrasive wear resistanc...
Pulikeshi, K. H.; Goudar, Dayanand M.; Kurahatti, R. V.; Pinto, Deesy G.; Pinto, Deesy<jats:p>Fabric-reinforced hybrid polymer composites are present in almost every sector of modern life, and most essential areas of research in recent years have focused on glass–carbon fabric with filler material composites. Fabric and fillers are employed in strengthening polymer composites with the aim of improving their mechanical and tribological properties. The primary objective of this investigation was t...
Effect of nickel on the mechanical properties of spray-formed Al-15Si-2Cu alloy...
Goudar, Dayanand M.; Alavandi, Mehabubsubahani R.; Bhat, Subraya Krishna; Bommenahalli, Raghukumar; Kurahatti, Rajashekar V.; Pinto, Deesy G.; Raju, K.at different temperatures was examined and evaluated with that of the as-cast (AC) alloy. The microstructure of SF alloys revealed uniformly distributed spherical shaped primary silicon and eutectic silicon phases along with fine Ni and Cu intermetallic particles dispersed throughout the equiaxed Al matrix. The microstructure of AC alloys consisted of coarse primary Si, flake-type eutectic phase, Cu-rich interm...
Enhancing the interfacial adhesion and mechanical strength of pultruded ECR–gla...
Chandra, Poorna; Venkatarayappa, Ravikumar; Chandrashekar, Savitha D.; Raveendra, Kiran; Bhaskararao, Asha P.; Bheemappa, Suresha; Goudar, Dayanand M.<jats:p>The effect of the interaction between silica (nS) and hydroxyapatite (nHap) nanomaterials on the characteristics of unidirectional glass-fiber-reinforced epoxy (GF/Ep) composite systems is investigated in this work. The goal of the study is to use these nanofillers to improve the microstructure and mechanical characteristics. Pultrusion was used to produce hybrid nanocomposites while keeping the GF load...
Effect of sintering temperature on the physical and mechanical characteristics ...
Saini, Brajesh Chandra; Jain, Naman; Rao, Dinesh Kumar; Singhal, Varun; Verma, Akarsh; Goudar, Dayanand M.; Raju, Kandavalli; Pinto, Deesy G.<jats:p>The present study investigates the synthesis and characterization of a zirconium oxide (ZrO2)-based metal composite doped with cerium (Ce) and yttrium (Y), using chromium (Cr) and nickel (Ni) as base metals. These constituents were selected for their superior mechanical properties and compatibility with the ceramic phase. High-purity powders were homogenized via high-energy ball milling, followed by col...
Influence of Cu addition on the wear behavior of a Eutectic Al–12.6Si alloy dev...
Goudar, Dayanand M.; Haider, Julfikar; Raju, K.; Kurahatti, Rajashekar V.; Pinto, Deesy G.; Pinto, Deesy<jats:p>In the present study, the influence of the addition of copper (Cu) on the wear behavior of a Al-12.6Si eutectic alloy developed using the spray forming (SF) method was discussed, and the results were compared with those of as-cast (AC) alloys. The microstructural features of the alloys were examined using both optical and the scanning electron microscopy, and the chemical composition and phase identific...
Experimental Study on the Surface Properties of Nanoalumina-Filled Epoxy Resin ...
Pinto, Deesy; Amaro, Ana M.; Bernardo, LuísThis article presents an experimental study on the surface properties of epoxy resin nanocomposites (EPNCs) manufactured with a thermosetting epoxy resin (EP)–bisphenolAdiglycidyl ether (BADGE)–2-[[4-[2-[4-(Oxiran-2-ylmethoxy)phenyl]propan-2-yl]phenoxy]methyl]oxirane) and filled with alumina nanoparticles (NPs). The NPs consist of pretreated (with a silane agent) alpha alumina with irregular shapes and a 100nmm...
