Electrochemical Study of Ni20Cr Coatings Applied by HVOF Process in ZnCl2‐KCl at High Temperatures

Journal of Analytical Methods in Chemistry, Volume 2014, Issue 1, 2014., 2014
Corrosion behavior of Ni20Cr coatings deposited by HVOF (high velocity oxygen‐fuel) process was evaluated in ZnCl2‐KCl (1 : 1 mole ratio) molten salts. Electrochemical techniques employed were potentiodynamic polarization curves, open circuit potential, and linear polarization resistance (LPR) measurements.

High Temperature Corrosion of Inconel 600 in NaCl‐KCl Molten Salts

Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014
In this work the corrosion resistance of a high content nickel alloy, Inconel 600, was investigated in mixed NaCl‐KCl salts at 700, 800, and 900°C for 100 hours in static air. Investigation was carried out using electrochemical techniques such as polarization curves, rest potential measurements, linear polarization resistance, and electrochemical ...

Corrosion Behavior of Pure Cr, Ni, and Fe Exposed to Molten Salts at High Temperature

Advances in Materials Science and Engineering, Volume 2014, Issue 1, 2014., 2014
Corrosion resistance of pure Fe, Cr, and Ni materials exposed in NaVO3 molten salt at 700°C was evaluated in static air during 100 hours. The corrosion resistance was determined using potentiodynamic polarization, open circuit potential, and lineal polarization resistance. The conventional weight loss method (WLM) was also used during 100 hours.

Phase Stability Diagrams for High Temperature Corrosion Processes

Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
Corrosion phenomena of metals by fused salts depend on chemical composition of the melt and environmental conditions of the system. Detail knowledge of chemistry and thermodynamic of aggressive species formed during the corrosion process is essential for a better understanding of materials degradation exposed to high temperature.

Main Characteristics of Mexico City Local Wind Events during the MILAGRO 2006 Campaign within a Meso‐β Scale Lattice Wind Modeling Approach

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
A characterization of local wind events in Mexico City, which occurred during MILAGRO campaign, was carried out within the framework of a lattice wind modeling approach at a meso‐β scale. Mexico City was modeled as a 2D lattice domain with a given number of identical cells. Local wind conditions at any cell were described by a state variable defined by
