Mechanisms of Hot Corrosion

1982
This paper reviews the results of hot corrosion mechanisms research carried out in Round 2 of COST 50 and sets it in relation to contemporary research outside COST 50.

Titanium Corrosion by a Hot Perfluoropolyether

Corrosion, 1980
The kinetics and mechanism of titanium corrosion by Krytox MLO-71-6 are reported. The rate of corrosion is found to be dependent on the presence of molecular oxygen in the environment. For titanium corrosion to occur, the lubricant chains must first break down into smaller reactive molecules.

Microcell processes in hot corrosion

Corrosion Science, 1993
Abstract It has been proved that there exists a microcell process in hot corrosion. The microcell is mainly determined by inhomogeneities and defect properties in the oxide film formed on the surface of the metal or alloy during hot corrosion. Three experimental methods have been used to prove the above mechanism.

Hot Corrosion of Protective Coatings

Materials and Manufacturing Processes, 2000
Abstract Abstract Improvement in efficiencies of gas turbine engines requires a significant increase of gas inlet temperatures. This results in an increased service temperature for blade materials and consequently in enhanced oxidation and hot corrosion attack of the blade coatings, which are usually of MCrAlY type where M is Ni, Co or NiCo.

Hot Corrosion of Oxide Ceramics

1994
The hot corrosion of oxide ceramics is described by examining the hot corrosion of A12O3, SiO2 and Y2O3 — stabilized ZrO2 in Na2SO4 and Na2SO4 — NaVO3 solutions at temperatures between 700° and 1000°C. Depending upon the properties of the molten deposit and the oxide ceramics a number of hot corrosion processes are possible. Acidic or basic dissolution

Hot Corrosion in Gas Turbines

2007
Abstract This chapter examines the hot corrosion resistance of various nickel- and cobalt-base alloys in gas turbines susceptible to high-temperature (Type I) and low-temperature (Type II) hot corrosion. Type I hot corrosion is typically characterized by a thick, porous layer of oxides with the underlying alloy matrix depleted in ...

The Increasing Complexity of Hot Corrosion

Journal of Engineering for Gas Turbines and Power, 2017
It has been conjectured that if sulfur in fuel is removed, engine materials will cease to experience attack from hot corrosion, since this sulfur has been viewed as the primary cause of hot corrosion and sulfidation. Historically, hot corrosion has been defined as an accelerated degradation process that generally involves deposition of corrosive ...

CORROSION INHIBITION IN DEEP, HOT WYOMING WELLS

Proceedings of SPE Rocky Mountain Regional Meeting, 1980
ABSTRACT Downhole inhibitor treatment of several relatively deep, hot gas wells in Wyoming was used in a study of factors to consider in establishing an effective corrosion control program. Basically, one needs an effective inhibitor, a good application method, and a means to evaluate the lifetime of the treatment.
