Characteristics of AISI 420 Stainless Steel Modified

In this research work, low-temperature carburizing of AISI 420 martensitic stainless steel was conducted at 460 °C for different amounts of time using an acetone source. The microstructure and phase structure of the carburized layers were characterized by optical microscope and X-ray diffraction. The properties of the carburized layers were tested with a microhardness tester and an Corrosion Behavior of Twin-Roll Cast Al-Mg and Al-Mg Keywords:Automotive aluminum sheet, corrosion, AA5754, AA6016 Abstract AlMg and AlMgSi alloys are used for automotive applications, where a good corrosion resistance is required. Recently, there has been a growing interest in using strip casting as a method to produce low-cost aluminum sheet for automotive applications. The present work

Corrosion Initiation and Propagation on Carburized

Mar 21, 2019 · Previous work by Schmutz and Frankel showed similar behavior on aluminum alloys and indicates that the shift in VPD observed on HTT following active corrosion was caused by oxide growth at cathodic sites and the generation and deposition of corrosion products at active sites creating a more homogenous surface . For carburized MSSs, the Corrosion Initiation and Propagation on Carburized Mar 21, 2019 · Previous work by Schmutz and Frankel showed similar behavior on aluminum alloys and indicates that the shift in VPD observed on HTT following active corrosion was caused by oxide growth at cathodic sites and the generation and deposition of corrosion products at active sites creating a more homogenous surface . For carburized MSSs, the Corrosion Resistance of Diamond-like Carbon-Coated The corrosion characteristics of diamond-like carbon (DLC) films, deposited on aluminum film-covered single-crystal silicon substrates were investigated using standard potentiometric methods. The DLC films were deposited by radio frequency (13.56 MHZ) plasma deposition from three different precursors, methane, acetylene, and 1,3 butadiene, with argon or hydrogen as the diluent.

Corrosion Resistance of Diamond-like Carbon-Coated

The corrosion characteristics of diamond-like carbon (DLC) films, deposited on aluminum film-covered single-crystal silicon substrates were investigated using standard potentiometric methods. The DLC films were deposited by radio frequency (13.56 MHZ) plasma deposition from three different precursors, methane, acetylene, and 1,3 butadiene, with argon or hydrogen as the diluent. Corrosion and tribocorrosion behavior of W doped DLC Nov 01, 2020 · It is clear that all the coatings present better corrosion-resistance performance than uncoated steel by showing lower current densities (I corr) and higher corrosion potentials (E corr). Furthermore, for uncoated steel, there is a break-down potential at higher potential, indicating the formation of pitting. Corrosion of Aluminum and its Alloys in Superheated Steam The corrosion behavior of pure aluminum and some of its alloys in superheated steam was found to depend markedly on the method of starting the corrosion test. Pure aluminum samples survived only in tests that were brought to temperature and pressure very rapidly. Resistant Al-- Ni-- Fe alloys performed well only if a relatively slow starting procedure was used, suffering extensive blistering

Effect of Cold Forming on Low-Temperature Plasma

measured using FERITSCOPE MP30 (made by Fisher Instruments). Plasma nitriding or carburizing was performed with a laboratory-type apparatus with a conventional direct current (dc) power source. After the specimen was mounted on the cathode in a furnace, its vacuum bell jar was evacuated to 1.33 110 Pa. The specimens were plasma nitrided in a gas Effect of Cold Forming on LowTemperature Plasma Oct 28, 2009 · Therefore, to apply lowtemperature plasma processing to parts made of stainless steels, it is important to clarify the nitriding and carburizing behavior of the coldformed structure. In this study, we investigated the effect of coldformed structure on the thickness of the plasma nitrided layer and carburized layer on the austenitic Effect of Impact Angle on Slurry Erosion Behavior and The paper reports the influence of carburizing on the slurry erosion behavior of AISI 5117 steel using a whirling-arm rig. The microstructure and hardness profile of the surface layer of carburized

Effect of nanograinboundary networks generation on

The morphology, phase, and corrosion behavior of steel are investigated using GIXRD, XANES, and EIS. The results show formation of nanograinboundary networks in the protective layer of Intergranular Oxidation (IGO) / Intergranular Attack (IGA)May 12, 2017 · Fig. 3. Vacuum Carburized Component with No IGO Present (Compare and Contrast with Figure 1) Other aluminum-based alloys are sensitive if there are layers of materials acting as anodes between the aluminum-rich areas. Intergranular corrosion is a concern especially for aluminum alloys with a high percentage of copper. NRC:Aluminum Chemistry in a Prototypical Post-Loss-of Mar 11, 2020 · Finally, the characterization of the particle sizes and corrosion properties, including the corrosion mechanism and the corrosion rate of aluminum under LOCA conditions, has been elucidated. The current study should allow for the development of a head-loss correlation using the existing cake filtration theory, which could be used in conjunction

Study of the SCC Behavior of 7075 Aluminum Alloy After

Apr 25, 2012 · For the past many years, 7075 aluminum alloys have been widely used especially in those applications for which high mechanical performances are required. It is well known that the alloy in the T6 condition is characterized by the highest ultimate and yield strengths, but, at the same time, by poor stress corrosion cracking (SCC) resistance. For this reason, in the aeronautic applications, new TheCorrosionBehaviorofCarburized Aug 17, 2011 · The corrosion properties of the untreated and plasma-carburized samples were evaluated using anodic polarization tests in 3N of corrosion tests also showed that corrosion behavior of Ed., Corrosion Of Aluminum And Aluminum Alloys, ASM International, 1999.
