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 ...

In this paper, application of ultrasonic techniques for defect detection in weldments of austenitic stainless steel and maraging steel is discussed. Applications of ultrasonic techniques for characterizing microstructural changes in AISI type 316 stainless steel and modified 9Cr-1Mo ferritic steel; thermomechanical processing of 15Cr-15Ni-2.3Mo-titanium modified austenitic stainless steel (allo...

ABSTRACT
 
 Two macro-roughness patterns namely spiral grooving and diamond knurling were performed on an AISI/SAE 1045 cylindrical steel bar. Al2O3 + 13 wt.-% TiO2 powder was deposited by utilizing a multi-pass torch. Microstructure, microhardness wear resistance analyzed. The presence of both γ-Al2O3 α-Al2O3 throughout the coating promoted partially melted un-melted particles; howev...

The study comprises evaluation of suitability of passive layer created on the surface of AISI 316L stainless steel for products that are intended to have contact with blood. For that purpose, prior to and after chemical passivation, samples were subject to 7 day exposure in artificial plasma at the temperature of T=37°C. Next, tests of metallic ions infiltration from the surface to the solution...

In this paper we study the corrosion of AISI 304 austenitic stainless steel PEMFC bipolar plates in aqueous and room-temperature ionic-liquid electrolytes. The anodic potential thresholds and dynamics have been investigated by electrochemical (potentiodynamic and potentiostatic) and in situ spectroelectrochemical methods (visible electroreflectance and VIS-UV spectroellipsometry). We measured t...

In this study, the tribological properties of three AISI 1045 steel samples were investigated. Two treated with ultrasonic shot peening (USP) and strengthening grinding process (USGP), respectively, while other one was only a polishing process. Sample properties, such as surface morphology, roughness, microhardness, elastic modulus, frictional coefficient, phase structures analyzed. Results sho...

In this research, the TiC–Ni35A composite coating was fabricated on AISI 1045 steel substrate by laser cladding process. The cross-sectional morphology, microstructure, microhardness, and wear resistance of coatings obtained under different energy densities (E) TiC powder ratios (PR) were analyzed. According to results, all had a reliable metallurgical bonding with substrate. X-ray diffraction ...

Corrosion is one of the major problems in the industry especially on machinery since it weakens the structure of the machinery part and causes the mechanical failure. This will stop the production and increase the maintenance cost. In this study, the corrosion behaviour of gas nitriding on a screw press machine shaft made from AISI 4140 steel was investigated. Pitting corrosion was identified a...

This paper presents a numerical investigation of the effects chamfered and sharp cemented carbide tools using finite element method-based DEFORM-2D software cutting parameters on different machining characteristics during orthogonal AISI 1045 steel. The objective is to study interactions between chamfer width, angle, angle speed feed rate temperature, effective stress wear depth. These were inv...

in this paper, welding feasibility between aa1100, aa5050 and aa6082 aluminum alloys and a441 aisi steel by friction stir welding has been studied. mathematical analysis of the heat generation during process showed that the maximum temperature produced in aa6082 aluminum alloy and a441 aisi joint but heat distribution in aa1100 aluminum alloy was higher than the other alloys. the investigation ...
