As the structure of biofilms plays a key role in their resistance and persistence, this work presents for the first time the numerical characterization of the temporal evolution of biofilm structures formed by three Listeria monocytogenes strains on two types of stainless-steel supports, AISI 304 SS No. 2B and AISI 316 SS No. 2R. Counting methods, motility tests, fluorescence microscopy and ima...

Abstract: The investigation is carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials: the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steel 310. This paper describes the effects of aging treatment on the joint. The compara...

Abstract The "Gold Dust Defect" affects the surface quality of AISI 430 ferritic stainless steels. However, there is a very limited number studies focusing on it. To better understand its nature, we have combined several techniques, such as x-ray photoelectron spectroscopy, atomic force microscopy, and transmission electron in order to extract maximum structural compositional information. Our r...

INVESTIGATING THE EFFECT OF WELDING PASTE CONTAINING GRAPHENE NANOSHEETS ON BONDING PROPERTIES WELDED AISI 304 STAINLESS STEEL PRODUCED BY FLUX-CORED ARC

It is well known that during tensile testing, a part of the mechanical work done on the specimen is transformed into heat energy. The rate of rise and maximum temperature attained depends on the nature of material, its deformation behaviour and test conditions. This paper highlights the application of thermography for characterising various stages of tensile deformation in AISI type 316 stainle...

The corrosion and cell viability behaviors of nanostructured, nickel-free stainless steel implants were studied and compared with AISI 316L. The electrochemical studies were conducted by potentiodynamic polarization and electrochemical impedance spectroscopic measurements in a simulated body fluid. Cytocompatibility was also evaluated by the adhesion behavior of adult human stem cells on the su...
