Abstract Nowadays, research on additive manufacturing of Ti6Al4V alloy is growing exponentially but there are just a few studies about metal matrix composite components. In this work, highly reinforced composites with SiC particles have been additively manufactured by direct laser deposition (DLD). powder and deposited layer to form an thin wall structure. The geometry, microstructure, microhardness the samples strongly influenced scanning speed used during de fabrication process. addition,...
Disulfide containing vitrimers are being widely studied to get renewable, reprocessable and self-healable resins. The most of them based on thermally cured epoxy resin. Herein, new thermoset systems typical acrylate monomers with photo-curing were synthesized self-healing capabilities by introducing disulfide bonds. These groups able exchange upon heating, leading a renewal the crosslinks across damaged surfaces. Different ratios associative reversible covalent bonds have been studied....
This study shows that WC-12Co coatings with low porosity and high wear corrosion resistance can be applied by velocity oxygen-fuel (HVOF) on a melting highly flammable ZE41 magnesium alloy. provides novel promising use of the high-energy thermal spraying technique temperature substrates. The distance used was 300 mm, which is between two three times recommended distanced for HVOF coating steels. Despite this, obtained were homogeneous, crack-free, dense. very well adhered to substrates...
Industry has a growing need of advanced coatings for variety applications (aerospace, special machinery, medicine, etc.). Nanostructured have the potential providing novel materials with enhanced properties. This paper describes results recent research on wear-resistant nanostructured coatings. Cermet (WC–Co) and ceramic (Al2O3–TiO2) were obtained by atmospheric plasma spraying. Coating microstructure phase composition characterized using scanning electron microscopy, X-ray energy-dispersion...
In this article, a preliminary microscale study of brazed joint two materials that will conform the future fusion reactors is carried out. Tungsten act as plasma-facing material attached to structure made some reduced activation ferritic-martensitic steel (Eurofer-like steel). The proposed brazing process introduces copper filler and develops thermal in high vacuum atmosphere at 1135 °C for 10 min. resultant microstructure characterised by forming diffusion layer contact with tungsten base...
Ti6Al4V is the most used alloy for implants because of its excellent biocompatibility; however, low wear resistance limits use in biomedical industry. The additive manufacturing (AM) a well-established technique that being many fields. However, AM composites currently under investigation, and manufacture using laser powder bed fusion (L-PBF) would result great benefit industries. one-step novel concept proposed uses gas-controlled L-PBF system enables layers with different compositions. Six...
In this work ultrafine and nanocrystalline WC–Co mixtures were obtained by low energy milling in planetary ball mill. The effect of the processing conditions on reduction distribution grain sizes internal strains level studied. characterisation powder was performed means scanning transmission electron microscopy X-ray diffraction analysis. Observations through SEM TEM images showed a particle size below 100 nm, after milling. profile analysis revealed WC phase refined to crystallite 19 nm.

Thermal sprayed WC-Co coatings are used extensively to enhance the wear resistance of a wide range engineering components. In this paper, erosive plasma atmospheric WC-12Co has been evaluated. Solid particle erosion tests were conducted on these at different angles impact with silica and alumina abrasives size 250 µm. Coatings have deposited by using micrometric nanometric agglomerated powders, employing H2 He as plasmogen gas. order determine regime (ductile or brittle), influence angle...
El objetivo de este trabajo es estudiar el comportamiento a desgaste distintos recubrimientos WC sobre acero inoxidable mediante proyección por plasma atmosférico.

Las uniones soldadas de aceros inoxidables siempre presentan problemas por las modificaciones microestructurales que suceden en la zona afectada el calor. Particularmente, los dúplex cambios muy importantes al solidificar cordón y formar estructuras, fundamentalmente ferríticas, con formación austenita borde grano. Estas microestructurales, junto a ZAC, son justifican propiedades mecánicas unión plasticidad. Y todo ello función condiciones procesado. En este trabajo se presenta influencia...
