SKPFM e microcélula eletroquímica para a avaliação do grau de passivação de soldas do aço inoxidável duplex 2101 / SKPFM and electrochemical microcell to the passivation level assessment of welds of 2101 stainless steel

Brazilian Journal of Business, 2022
O grau de passivação de juntas soldadas do aço inoxidável duplex 2101 foi avaliado em duas diferentes condições de soldagem TIG e aporte térmico: 2,4 kJ/mm (2,4T) e 1,5 kJ/mm (1,5 T). A caracterização microestrutural foi realizada por microscopia ótica e eletrônica de varredura, e o desempenho em corrosão foi avaliado por ensaios eletroquímicos de ...

Possible Luttinger liquid behavior of edge transport in monolayer transition metal dichalcogenide crystals. [PDF]

, 2020
In atomically-thin two-dimensional (2D) semiconductors, the nonuniformity in current flow due to its edge states may alter and even dictate the charge transport properties of the entire device.

A Comparative Investigation on the Corrosion Behavior of cast and rolled ZG21 Mg Alloys

International Journal of Electrochemical Science, 2017
ZG21 Mg alloys exhibit excellent deformation ability at room temperature. However, their corrosion behavior lacks sufficient investigation. The relationship between the second phases and micro-galvanic corrosion of ZG21 Mg alloys has been investigated ...

In-Situ Time-Lapse SKPFM Investigation of Sensitized AA5083 Aluminum Alloy to Understand Localized Corrosion

Journal of The Electrochemical Society, 2020
Sensitized AA5083-H2 aluminum alloy was exposed to chloride-laden thin-film electrolyte at ambient temperature (20%–85% relative humidity) and the local Volta potential measured,in-situand in real-time, using the Scanning Kelvin Probe Force Microscopy, with the intention to elucidate the earliest stage of localized corrosion.

Influence of Dichromate Ions on Corrosion Processes on Pure Magnesium [PDF]

, 2003
The corrosion behavior of Mg is of interest because of its growing use as an alloy in the transportation industry and also because it is a major component of some intermetallic phases in Al alloys, such as the deleterious S (Al2CuMg)-phase found in ...

Sub-Microscopic Phenomena of Metallic Corrosion Studied by a Combined Photoelectron Spectroscopy in Air (PESA) and Scanning Kelvin Probe Force Microscopy (SKPFM) Approach

International Journal of Electrochemical Science, 2012
The management of metallic corrosion has relied on large-scale, ultra-conservative protection strategies such as the extensive use of anti-corrosion metals and alloys, all-inclusive coating and surface passivation, and substantial use cathodic protection.

The Role of Cu-Based Intermetallic on the Direct Growth of a ZnAl LDH Film on AA2024 [PDF]

, 2022
The direct ZnAl layered double hydroxide growth on AA2024 is a fast-occurring reaction, yet is characterized by an inhomogeneous film thickness. It has been shown that at the periphery of Cu-rich intermetallic, the flakes tend to be larger and denser.

Improving corrosion resistance of Mg–Li alloys by Sn microalloying

Journal of Materials Research and Technology, 2023
It is well known that the corrosion resistance of ultra-light Mg–Li alloys is inferior to traditional Mg alloys due to the rapid oxidation of reactive Li on the surface.
