high-temperature corrosion

It is used for its excellent resistance to high-temperature corrosion and oxidation.

The products of high-temperature corrosion can potentially be turned to the advantage of the engineer.

The first two dealt with run-of-the-mill high-temperature corrosion tests.

High-temperature corrosion is chemical deterioration of a material (typically a metal) as a result of heating.

Soft and ductile, palladium is resistant to oxidation and high-temperature corrosion.

(1966) led to widespread use of MgO as a combustion additive to reduce high-temperature corrosion.

Good high-temperature corrosion resistance, possible alternative to Au-Pd brazes.

In combination with chlorine, a common trace element in coal and municipal waste, high-temperature corrosion by sulphur compounds continues to challenge metallurgical science.

This is particularly true of high-temperature corrosion, i.e., steam generator tubes operating at temperatures of 400ºC to 650ºC, in the presence of molten ash and oxides.

High-temperature corrosion is a mechanism of corrosion that takes place in gas turbines, diesel engines, furnaces or other machinery coming in contact with hot gas containing certain contaminants.

Such high-temperature corrosion products, in the form of compacted oxide layer glazes, prevent or reduce wear during high-temperature sliding contact of metallic (or metallic and ceramic) surfaces.

In earlier years, Mitchell, a specialist in high-temperature corrosion chemistry, had been forced to work in the program that was supposed to have led to the first German lunar landing in 1968.

(1975) as part of an extensive study of corrosion in municipal incinerators found that adding sulphur to the municipal waste substantially reduced high-temperature corrosion of carbon and stainless steels.

However, Brandel and Mousset (1973) using electron microprobes to examine high-temperature corrosion specimens from both coal- and oil- fired boilers found only oxides and sulphides at the corrosion front.

Therefore when combusted it emits neither SO2 nor SO3 , has no sulphur-related high-temperature corrosion problems, and having no problems with acid dewpoint, is amenable to high-efficiency condensing heat recovery.

COLUMBUS, Ohio, March 20 (UPI) -- U.S. engineers are developing a technique to coat jet engine turbine blades with zirconium dioxide, known as zirconia, to combat high-temperature corrosion.

This formed a thin layer of MgO on the exposed furnace and convection surfaces and was found to significantly reduce SO3 formation probably by inhibiting the catalytic effect of these surfaces. The authors surmized that the layer of MgO would also beneficially influence high-temperature corrosion.
