A three-dimensional model of a partially melted powder bed with particles stochastically distributed in size and space coordinates has been developed. Numerical simulation temperature distributions stainless steel AISI 316L Al-12Si powders vacuum, air argon performed to analyze unsteady heat transfer porous medium. The numerical demonstrates large effect through the gas phase case low thermal c...

The present research investigates the influence of surface roughness imparted by cold finishing processes on localized corrosion resistance stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic 430F, austenitic 303, 304L, and 316L. It was demonstrated that grinding process, executed previously drawn bars, leads to an improvement in according results obtained with e...

Titanium dioxide (TiO2) thin films are widely used in transparent optoelectronic devices due to their excellent properties, as well photocatalysis, cosmetics, and many other biomedical applications. In this work, TiO2 were deposited onto AISI 304 316L stainless steel substrates by atomic layer deposition, followed comparative evaluation of the mixture anatase rutile phase X-ray diffraction, Ram...

The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless steel depends on the passive layer. Herein, chemical surface treatment, including passiv...

Corrosion tests of 316L and two intermetallic compounds Fe3AI and FeCrSi in industrial Galvanizing (Zn-0.18Al), GALFAN (Zn-5AI), GALVALUME (Zn-55AI), and Aluminizing (AI-8Si) baths and lab-scale static baths were conducted. In on-line tests in industrial hot-dip baths, 316L steel shows better corrosion resistance than Fe3AI in Galvanizing, GALFAN, and GALVALUME baths. The corrosion resistance o...

Due to growing environmental concerns and economical social problems in manufacturing sectors, there is a huge demand for the substitution of existing cutting fluids. Further, fluids selected are expected reduce force, improve surface roughness also minimize tool wear during machining operations. Hence, this paper discusses tribological morphological behaviour AISI 316L stainless steel while tu...

Among all the additive manufacturing techniques, Laser Powder Bed Fusion (LBPF), also called Selective Melting (SLM), is most common technique due to its high capability of building complex parts with generally improved mechanical properties. One main drawbacks this sample size limitation, which depends on elaborating chamber dimensions. In study, we investigate viability obtaining large laser ...
