A Corrosion Protection Method for Preventing Corrosion Due to Inner-Jumping Current in High-Temperature, High-Pressure Water Pipelines.

Nitrogen and Water in High Temperature Corrosion

Service life-time of alloys used in high temperature applications is often limited by corrosion. FeCrAl(Re) alloys are partially designed to form a protective α-alumina oxide scale at elevated temperatures in order to mitigate further oxidation. The scale growth commonly follows a parabolic rate law, which under a Wagnerian setting depends on transport of charged species; ions, vacancies and el...

A method of specimen corrosion protection for high temperature creep testing

-The determination of mechanical properties of materials at elevated temperatu~; presents difficulties, particularly when the material to be tested is subject to oxidation. Various methods have been employed to permit the evaluation of high temperature creep properties. The method described in this paper was developed on the basis of modifications of a technique developed for the protection of ...

Corrosion Properties of F82H in Flowing High Temperature Pressurized Water

This work reports the effects of water flow and dissolved oxygen (DO) on corrosion behavior of reduced activation ferritic/martensitic steel, F82H. The corrosion tests were performed in high temperature pressurized water by using a test apparatus for rotated disk sample. All of specimens showed weight gains after static corrosion tests up to 500 h. However, the rotated disk showed weight losses...

High-temperature Corrosion in Power-generating Systems

Several technologies are being developed to convert coal into clean fuel for use in power generation. From the standpoint of component materials in these technologies, the environments created by coal conversion and their interactions with materials are of interest. Coal is a complex and relatively dirty fuel that contains varying amounts of sulfur and a substantial fraction of noncombustible m...
