One of the problems in the case of stainless steels is their low corrosion resistance against pitting corrosion in chloride containing environments, thereby leading to severe damage to industries. In this research, the pitting corrosion of 304 austenitic stainless steel was studied in 3.5% NaCl solution at room temperature (25˚C) by performing electrochemical measurements (containing cyclic pol...

tably strength, so corrosion resistance (stability) may not be the primary design consideration. Assemblies need to be strong and resilient to the unique loads and stresses imparted on them, which can include significant temperature changes and thermal gradients for many high-temperature applications. In making a choice, it is necessary to know what materials are available and to what extent th...

Introduction: During sliding mechanics, frictional resistance is an important counterforce to orthodontic tooth movement; which must be controlled to allow application of light continuous forces. objective: To investigate static and kinetic frictional resistance between three orthodontic brackets: ceramic, self-ligating, and stainless steel, and three 0.019×0.025” archwires: stainless steel, ni...

Changes in mechanical and corrosion properties caused by the development of radiationinduced microstructure have relevance to the aging and lifetime extension of light water reactors (LWR’S). However, much of the current data related to microstructural development in irradiated metals are generated from studies carried out at much higher dose-rates than encountered in LWR’S. An opportunity exis...

We report the preparation of TiO2 nanotubes coupled with a narrow bandgap semiconductor, i.e., Bi2S3, to improve the photocathodic protection property of TiO2 for metals under visible light. Bi2S3/TiO2 nanotube films were successfully synthesized using the successive ionic layer adsorption and reaction (SILAR) method. The morphology and structure of the composite films were studied by scanning ...

Last years analytical or finite element models of milling become more efficient and focus on more physical aspects, nevertheless the milling process is still experimentally unknown on a wide range of use. This paper propose to analyse with accuracy milling operations by investigating the cutting forces values, shape of cutting forces curves obtained for different cutting speeds, and related phe...

In the present work Taguchi method is used to optimize cutting parameters during dry turning of AISI 304 austenitic stainless steel with AlTiCrN coated tool. The coating was deposited on fine-grained K-grade (ISO K-20) cemented carbide cutting insert using physical vapor deposition (PVD) technique. The turning parameters evaluated are cutting speed of 200 and 260 m/min, feed rate of 0.20 and 0....

One of the main considerations in adopting additive manufacturing (AM) technology is whether material properties AM-produced part are comparable with wrought material. This study compared 304 stainless steel via direct energy deposition (DED) AM process steel. The samples were studied their as-built or as-received condition; and characterisation analysis included micro-structural evaluation, ha...

The use of microplastics is a global issue that affects the environment, economy and human health. Here we describe superhydrophobic 304 stainless steel obtained by combining chemical etching PDMS modification. Among other techniques, field emission scanning electron microscopy (FE-SEM) high-resolution X-ray photoelectron spectroscopy (HR-XPS) were used to identify hierarchical structure as wel...
