In this paper, the semiconducting behavior of carbon steel in acid, base and salt solutions was studied by utilizing potential-capacitance and Mott-Schottky analysis. It was pointed out that the capacitance variation of space charge layer of carbon steel in different solution was different. The carbon steel showed p-type semiconducting behavior in 5% sulfuric acid and 5% sodium sulfate solution...

The aim of this study was to analyse the peel resistance of silver plated wires examined in an intraoral setting. In this study, a 0.016 × 0.016 inch silver plated stainless steel wire and a 0.016 × 0.016 inch Teflon-coated nickel-titanium wire were investigated. The brackets of ceramic and stainless steel were bonded to the first and second bicuspids of two subjects. We investigated peel resis...

This study is a detailed failure analysis of galvanized high carbon steel wires, which developed coating cracks during the torsion test performed as a quality control at the end of the manufacturing process. Careful visual inspections showed that the cracks are already present in the coating before the torsion test. In order to explain the origin of these cracks, systematic metallographic inves...

structural steels with very high strength levels are often referred to as ultrahigh-strength steels (uhss). the usage of uhss has been extensively studied in aerospace industries and offshore platforms. in this study, medium carbon low alloy steel (ams6305) was thermomechanicaly treated to obtain an ultra-high strength bainitic steel for aircraft engine compressor disk. a novel themomechanical ...

background: the aim of this study was to evaluate the response of common sized fiber-reinforced composites (frcs) to different deflections due to bending forces and comparing it with stainless steel (ss) wires. materials and methods: in this experimental study, two frc groups with 0.75 mm and 1.2 mm diameters (everstick ortho, stick tech, finland) and three ss groups with 0.016 × 0.022 inch, 0....

The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG). In the present work, bead-on -plate welds were carried out on MS 5986 Fe 410 carbon steel sheets using Gas Metal Arc Welding (GMAW) process. In this present investigation ER70S-6 solid wire having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity....

Abstract Forging dies are crucial in forging to manufacture accurate workpieces. These generally made of AISI H steel series and hardened tempered medium carbon alloy steel. Dies processed by using high-speed milling + polishing or electrical discharge machining polishing. The surface quality the workpiece depends on properties these dies, where roughness, material hardness, wear evolution thei...

INTRODUCTION The aim of this in-vitro study was to evaluate the frictional forces generated by various combinations of brackets and orthodontic wires by using an experimental model with 3 nonleveled brackets to gain a better understanding of the resistance to sliding during dental alignment and leveling. METHODS Two kinds of orthodontic brackets were tested: passive self-ligating brackets and...
