nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

Molten LiCl-KCl salt and liquid cadmium are proposed as the electrolyte reactive cathode for electrorefining of spent nuclear fuels, but they can be corrosive to structural alloys. The down-selection existing materials through corrosion testing is necessary ensure longevity electrorefiner vessel electrode assemblies. Haynes C276, Inconel 600, AISI 316L stainless steel, 42CrMo low-alloy steel we...

This study examines the effect of tensile test temperatures ranging from 50°C to 600°C on the tensile properties of a modified 9Cr-1Mo ferritic steel (T91) and a 316L stainless steel (SS) after high energy proton irradiation at about 35°C-67°C. After 1-3 dpa, the proton-irradiated T91 steel was tensile tested at temperatures from 50°C to 600°C. It was observed that the yield strength and ultima...

A contactless temperature measurement system is presented based on a hyperspectral line camera that captures the spectra in the visible and near infrared (VNIR) region of a large set of closely spaced points. The measured spectra are used in a nonlinear least squares optimization routine to calculate a one-dimensional temperature profile with high spatial resolution. Measurements of a liquid me...

The methodology in interventional cardiology has historically evolved from diagnostic coronary angiography to balloon angioplasty, to the use of bare metal stents (BmSs), to their refinement to drug-eluting stents with a durable polymer, and is now on the verge of drug-eluting stents with further developed drug delivery approaches such as reservoir technology and the use of bioresorbable polyme...

Sol-gel titania films were deposited on 316L stainless steel using titanium isopropoxide as a chemical precursor. Dipcoating was performed at withdrawal speeds of 6 mm/min, 30 mm/min, and 60 mm/min. Deposited gel films were heat treated in air at 80 ̊C, 100 ̊C, 300 ̊C, and 400 ̊C. The structural evolution of the coatings was evaluated by infrared reflection-absorption spectroscopy. The influence of...

In this investigation, Ti/TiN nanolayer and TiN single layer coatings were coated on substrate of AISI 316L stainless steel by applying physical vapor deposition (PVD) using the type of cathodic arc evaporation (CAE). The evaluation of microstructure were carried out using x-ray diffraction (XRD), nanoindentation, atomic force microscopy (AFM) as well as scanning electron microscopy (SEM). Pola...
