The TiO2–SiO2 thin films were deposited on AISI 316L stainless steel via sol-gel method. Then, the effect of the added amount of SiO2 on the structure, morphology and mechanical properties of the films and corrosion behavior of AISI 316L stainless steel substrate were investigated. So, X-ray diffraction, field-emission scanning electron microscopy, atomic force microscopy, depth-sensing indenta...

The lifetime of structural components of spallation targets (beam window, liquid metal container, return hull) is determined by the irradiation-induced changes of the mechanical properties of their materials. An extensive test program was initiated using specimens obtained from spent target components from operating spallation facilities (Los Alamos Neutron Science Center, LANSCE and the Spalla...

In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

Long–term stability and oxidation resistance of AISI 439 ferritic stainless steel used as interconnects in solid oxide fuel cells can be improved by use of a protective coating. In this study the pack cementation method was employed to coat AISI 439 ferritic stainless steel with manganese. Isothermal oxidation was conducted at 800 ºC for 200 hours in static air to investigate the role of coatin...

magnetic abrasive finishing (maf) is a micromachining process that uses magnetic field and magnetic abrasive particles to conduct the mechanism of material removal in micro-nanometer scales. in this paper, by an experimental method and statistical analysis, the effects of parameters like working gap, work-piece rotational speed and material removal mechanism (injection of abrasive slurry of al2...
