Investigation on the acoustic properties of structural gradient 316L stainless steel hollow spheres composites

نویسندگان

چکیده

Abstract In this study, a kind of structural gradient metal hollow spheres composites (SG-MHSCs) were fabricated using two kinds 316L stainless steel with different diameters and A356 aluminum through the casting method. Then density SG-MHSCs was measured by direct measurement; microstructure characterized Scanning Electron Microscope. Meanwhile, acoustic performance MHSCs tested impedance tube, sound absorption insulation mechanism discussed analyzed.

Biomaterial Studies on AISI 316L Stainless Steel after Magnetoelectropolishing

The polarisation characteristics of the electropolishing process in a magnetic field (MEP – magnetoelectropolishing), in comparison with those obtained under standard/conventional process (EP) conditions, have been obtained. The occurrence of an EP plateau has been observed in view of the optimization of MEP process. Up-to-date stainless steel surface studies always indicated some amount of fre...

An investigation on the passivation behavior of nitrogen enriched AISI 316L austenitic stainless steel

In the present work the effects of plasma nitridization on the passivation behavior of AISI 316L was investigated. To do this; nitriding treatments were carried out at 420°C for 1, 2, 4 and 16 hours. The phase composition and structure of the nitrided layer were studied by Low Angle X-ray diffraction and Scanning Electron Microscopy. The hardness of samples also was evaluated by Vickers microha...

A Review on Surface Coatings on 316L Stainless Steel to Improve Biomedical Properties

Stainless steel 316L has widely used as bioimplants in cranial plates, dental implants, bone fracture fixation, prothestic joints. However, low wear resistance, in some cases susceptibility to pitting and crevice corrosion in body environment and release of toxic ions from the surface are the basic disadvantages which this material prone to be. It has still applied as a temporary biomaterial du...
