Abstract: O&G production corrosion challenges are not static phenomena. Fluid characteristics change over time, making systems less predictive for corrosion mitigation programs. Thus, methods based on technology and management can be considered corrosion prevention solutions. Even though few studies of oil/water/gas mixtures in multiphase-flow (MF) conditions are found in the Leia mais…
Abstract: Conservation of natural resources is the basis of sustainability, which aims to achieve a balance between the resources and economic activity, and, in this context, the use of NdFeB-based magnets mainly enables sustainable power generation in particular. These magnetic alloys are susceptible to corrosion and require protection. This study Leia mais…
Abstract: A flexible pipe/riser is constructed using a polymer sealant that contains the density fluid,multiple helical layers that give the pipe the necessary strength and an outer polymeric layerthat prevents its contact with seawater. This configuration allows greater flexibility than rigidrisers with the same pressure capacity [1]. One of the Leia mais…
Resumo: O presente estudo avaliou a influência da temperatura na corrosão influenciada por microrganismos (CIM) sob condição estática e anaeróbica (~10 ppb) por um período de 45 dias. Os ensaios foram realizados em biorreatores e como meio foi utilizado água do mar natural esterilizada e enriquecida com solução nutritiva, em Leia mais…

Abstract: This study investigates the impact of the cooling rates, from 18 to 1.5 °C/s, on the as-cast microstructure of the CMSX-4 Ni-based superalloy, especially on morphological changes in primary γ′ precipitates in the dendrite core and border. Microstructural characterization along the height of directionally solidified samples included the measurement Leia mais…
Abstract: Fatigue behaviour of bcc Nb-48 wt%Ti (Ti-36at%Nb) alloy parts processed by Laser Powder Bed Fusion (L-PBF) using as raw material two different types of powders, spherical powder produced by Plasma Atomization (PA) and irregularly shaped powder produced by Hydride-Dehydride (HDH) process, are compared. Laser power and scanning speed were Leia mais…
Abstract: Microstructures of a single layer AISI M4 high speed steel deposited on a AISI D2 tool steel substrate using the L-DED process with two levels of global energy density were characterized and compared. A five-axes PRECO-SL 8600 CNC machine was used to deposit the M4 powder feedstock with a Leia mais…
