Current global 3D metal printing research is focused on powder bed fusion and direct energy deposition. Several materials are presently under to assess their post-additive manufacturing properties, process them in industries using advanced techniques. This study investigates the electrochemical, mechanical, metallurgical properties of wire arc additively manufactured (WAAM) ER70S-6 alloy walls AISI S235 plates, emphasizing ship component fabrication. The corrosion resistance both assessed...
Purpose This study aims to investigate the effect of copper and titanium micropowder addition on mechanical metallurgical properties additively manufactured low-carbon steel, aiming produce a modified (multiphase) steel with ferritic using in situ during wire arc direct energy deposition (WA-DED). Design/methodology/approach A robotic arm equipped GMA welding source deposited ER70S6 filler AISI S235 substrate WA-DED. Cu Ti micropowders were interspersed between layers for microstructural...
Stellite 6, a cobalt based superalloy was deposited on mild steel AISI 1020 using Gas tungsten arc welding (GTAW) process. The claddings were overlaid in four conditions viz. single layer cladding, double cladding with remelting and remelting, where of the topmost carried out autogeneous GTA itself. chemical composition, microstructure, wear mechanism phase composition substrate coatings characterized by spectroscopy, optical microscopy, scanning electron energy dispersive spectroscopy x-ray...
Wire Arc Additive Manufacturing (WAAM) is an advanced manufacturing technique capable of a high deposition rate and used for fabricating large-sized complex components. Of specific interest in the recent past in-situ micropowder alloying during filler material to modify properties each deposited layer. This study focuses on investigating metallurgical mechanical characteristics steel produced through powder-added WAAM, using characterization techniques such as optical microscopy, scanning...
