Effect of Width of Gas/Liquid/Solid Three-Phase Boundary Zone of Discrete Water Film on Atmospheric Corrosion of Metals

چکیده
The influence of potential on contact angle and the effect of TPB width on the cathodic corrosion processes of metals were studied by steady polarization and EIS technique combined with contact angle measurement. It is found that both cathodic limiting current density and corrosion current density linearly increases with increasing the TPB width, confirming the important role of TPB width in gas/liquid/solid multiphase corrosion systems. Based on above results, the effect of water film thickness on atmospheric corrosion rate was quantitatively evaluated by the TPB width.

Atmospheric corrosion
Atmospheric corrosion, the most common form of metal corrosion, occurs within the interfacial region between a solid, and the surrounding atmosphere. In fact three phases and two interfaces are involved: the gas, a thin liquid layer, a solid, the gas/liquid and the liquid/solid interfaces. In this thesis, the vapor/liquid and liquid/metal interfaces have been studied by the in-situ techniques v...
متن کاملThermal Simulation of Solidification Process in Continuous Casting
In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
متن کاملTransient liquid phase bonding of AISI 304L stainless steels with the austenitic and martensitic microstructures
In the present study, the effect of time and base metal microstructure on the Transient Liquid Phase (TLP) bonding of 304L stainless steel was studied. TLP was performed at 1050 0C for 5 and 60 minutes on the coarse grain austenitic and martensitic microstructure using BNi-2 interlayer. To prepare martensitic microstructure, as-received 304L was rolled at -15 0C up to 80% rolling reduction. TEM...

متن کاملTowards an Analytical Model for Film Cooling Prediction using Integral Turbulent Boundary layer
The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing ...
