Nanomaterials are integrated within consumer products to enhance specific properties of interest. Their release throughout the lifecycle nano-enabled raises concerns; specifically, mechanical strains can lead generation fragmented materials containing nanomaterials. We investigated potential single-walled carbon nanotubes (SWCNTs—brand TUBALL™) from epoxy composite materials. A pin-on-disk-type tribometer was used for accelerated aging nanocomposites. pristine nanocomposite material, abraded...
The performance enhancement of Thermal Barrier Coatings (TBC) towards higher service temperatures and longer life will have a tremendous positive impact on the energy efficiency turbines for various applications. In this work study evaluation LaAlO3 as an overlayer to YSZ-based TBC is presented. Overlayers TBC, are desirable in order add functionalities, not exhibited by YSZ, such CMAS tolerance. However, their effect thermal cycling multi-layered system needs be examined. NiCrAlY...
The objective of this study is to develop a cost-effective and environmentally friendly synthesis using soft chemistry based on Chemical Solution Deposition (CSD) ink-jet printing for the deposition ceramic thin films.The main advantages are lower investment, faster with higher yield processing under ambient pressure enabling complete continuous processing.The materials chosen TiO 2 development photocatalytic layers; Yttria-stabilized zirconia (YSZ) as electrolyte material Solid Oxide Fuel...
Abstract The study of self-lubricant coatings is a rapidly developing research field that expected to address major issues arising from operation under high loads and thermal stresses machine parts. It utmost importance various critical tribological pairs such as crankshaft bearings, piston rings, etc. maintain their integrity, thus contributing the engines efficient reliable for long periods time. Therefore, choice high-strength metals required, with special treatments and/or in combination...
Hip joint surgeries, including total hip replacement or resurfacing, have increased tremendously in the last decades. Number of patients all ages, replace their hip, due to severe injuries trauma problems, so as a better life. According these factors, new material and processes implants manufacturing are imported medicine, through research programs, every year. In scope one that has do with ceramic coatings on metallic resurfacing implants, 3axis simulator was designed manufactured...
The development of superconducting YBa2Cu3O7-x plasma sprayed coatings on metal substrates can be very useful for applications such as targets thin-film deposition techniques (sputtering, laser ablation, ion assisted deposition) or magnetic shielding, due to the brittle nature bulk superconductors. spraying technique is flexible and used manufacturing components with a large variety geometries. This requires use powders good rheological characteristics. In this study, were produced by using...
Abstract In this study, solution precursor plasma spraying is used to produce LaAlO3 perovskite topcoats for thermal barrier coating systems. precursors were prepared by in situ polymerization and deposited under different conditions order determine the effect of parameters on process yield, deposition rate, microstructure, hardness. Preliminary results with rates 5-20 μm/pass yields range 35-60% are presented. It shown that low feed high power, medium atomization gas flow rate result...
Abstract Composite coatings using mixed alloy matrices reinforced with carbon-based solid lubricants as feedstock materials were prepared by atmospheric plasma spraying. The aim of the present study was to investigate tribological characteristics such exploring potential benefits CNTs nano-additive reduce friction and wear, improving lubrication conditions during operation in tribosystems, piston ring – cylinder liner systems. chemical composition thermal spray parameters deposition are...
Spray drying is a technique used for the production of powders with high chemical homogeneity, consisting spherical shaped grains well-controlled particle size distribution, which show very good rheological characteristics. In present study, spray was employed homogeneous precursor powder synthesis superconducting YBa2Cu3O7−x powder. The concerned either solution nitrate salts or slurry oxides, showed that both characteristics and process yield depend significantly on parameters maximum can...
