Abstract: The O&G production corrosion challenges are not static phenomena. Fluid characteristics change over time, resulting in systems becoming less predictive for corrosion mitigation programs. Thus, carrying out specific studies aimed at understanding the corrosion mechanisms is constant in this sector, especially for offshore environments. Even though, few studies of Leia mais…

Resumo: A soldagem por Fricção e mistura linear é um dos processos de soldagem onde não há fusão do material base, de modo que alguns problemas geralmente associados com processos de soldagem são evitados, tais como trincas a quente e porosidades. Este trabalho tem como objetivo avaliar os impactos do Leia mais…
Abstract: Carbon fiber-reinforced polymers (CFRP) are extensively applied in the automotive and aeronautic industry due to several advantages that combine resistance properties with the weight reduction of components. The fiber reinforced thermoset composites are generally manufactured in components close to the final dimensions, and, therefore, need to be machined to Leia mais…
Abstract: This paper presents the effects of Niobium additions (1, 2 and 3%) on the wear resistance and impact properties of Hadfield steels (1.2%C and 12-18%Mn). The additions of Nb promoted a significant decrease in the mass losses, from 79 mg (Hadfield steel with 12%Mn) to 33 mg (Hadfield steel Leia mais…

Abstract: Occupational exposure to toxic elements can adversely affect health. The current study evaluated blood concentrations of potentially toxic elements (PTE) including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, and Zn in formal and informal workers. Additionally, the study investigated the associations between blood PTE concentrations and Leia mais…
IPT e Petrobras desenvolveram projeto para realizar estudos de corrosão em atmosferas reais de exposição O crescimento da demanda energética, a prospecção e a exploração de petróleo e o transporte de produtos brutos e derivados (petróleo bruto, nafta, gasolina e diesel, entre outros) têm exigido estudos permanentes com novos materiais Leia mais…
