the effect of chloride ions concentration on the electrochemical behavior of aisi 410 stainless steel in thesimulated concrete pore (0.1 m naoh + 0.1 m koh) solution was investigated by various electrochemicalmethods such as potentiodynamic polarization, mott–schottky analysis and electrochemical impedancespectroscopy (eis). potentiodynamic polarization curves revealed that increasing chloride ...

This article is devoted to the study of effect ion sputtering on alloy surface, using example martensitic stainless steel AISI 420 with ultrahigh-dose, high-intensity nitrogen implantation efficiency accumulation and transformation depth distribution dopants. Some patterns change in doping depending target temperature range from 400 650 °C, current density 55 250 mA/cm2, fluence up 4.5 × 1021 i...

Martensitic-grade stainless steels are widely used in diverse industrial and surgical applications, despite their natural tendency to suffer local uniform corrosion when continuously exposed aggressive operation conditions. In order enhance surface properties, this paper characterized the performance, saline solutions, of AISI 420 steel, which was surface-modified by three-dimensional ion impla...

Release of nickel from nickel or nickel-plated metals, is often responsible for allergic contact dermatitis. However, the effect of nickel-bearing stainless steels is not weil known. ln this paper AISI 304, 316 and 430 type stainless steels, as weil as nickel and nickel-plated materials, are investigated. Three tests were carried out: electrochemical tests and leaching experiments in sodium chl...

A high quality joint between tool steel and stainless steel alloys is hard to achieve with the conventional welding process. In this study, a new process of joining semi-solid AISI D2 tool steel and AISI 304 stainless steel using a partial remelting method is proposed. Metallographic analysis and Vickers hardness tests were performed. The results obtained from investigating the basic geometries...

The conclusions of an experimental program involving altered tensile strength and microstructure of stainless compressor valve steel are described. The paper presents the results of measurements of ductility, corrosion resistance, bending fatigue strength and damping. Encouraging indications have been achieved concerning the possibilities to further improve the characteristics of current materi...

In the present work CO2 continuous laser welding process was successfully applied and optimized for joining a dissimilar AISI 316 stainless steel and AISI 1009 low carbon steel plates. Laser power, welding speed, and defocusing distance combinations were carefully selected with the objective of producing welded joint with complete penetration, minimum fusion zone size and acceptable welding pro...

The effect of chloride ions concentration on the electrochemical behavior of AISI 410 stainless steel in the simulated concrete pore (0.1 M NaOH + 0.1 M KOH) solution was investigated by various electrochemical methods such as Potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization curves revealed that increasing chlori...

Several alloys described as stainless steel which resist tarnish and corrosion in the mouth are being used for a variety of dental appliances and instruments. Probably the greatest application of stainless steel is for orthodontic arch wires and bands, while a more limited use is for temporary space maintainers and crown forms. Root-canal files and reamers designed for endodontic operations als...
