The present work investigates the low-cost steels AISI 441, 430, and 444 against tailor-made high Cr steel Crofer 22 APU (22.9 wt% Cr) at 800 °C in simulated solid oxide fuel cell (SOFC) cathode conditions. Furthermore, a low steel, 409 (11.4 is included study. oxidation, chromium evaporation, area-specific resistance (ASR) of uncoated Ce/Co-coated are studied for up to 3000 h. showed significa...

A estampagem é um processo de conformação mecânica capaz gerar uma variada gama produtos, desde artefatos simples presentes no uso diário, como dobradiças e utensílios domésticos assim componentes complexos estruturas chassis aplicados setor automotivo. Neste contexto, o estudo do encruamento da distribuição deformação são informações essenciais para a escolha materiais, aplicaç...

In this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (AISI 316) and ferritic (AISI 430) stainless steel substrates have been investigated using torch technique. The effects of substrate surface preparation has also been studied. The quality of coatings produced has been examined using optical and scanning electron microscopy, X-ray diffraction, Raman spectros...

AISI 430 stainless steel is an attractive material to be used in the healthcare industry, particularly as a sensor due its low cost, corrosion resistance, well being Ni-free. was evaluated artificial sweat solution with presence of Escherichia coli, and Staphylococcus aureus. Surface microbial analyses did not reveal colonization bacteria on metallic surfaces, even when adhesion investigated Mü...
