Übersetzung für "Flächenkorrosion" in Englisch

Uniform surface corrosion is a form of corrosion with nearly uniform material loss rate on the entire surface.

The thus formed layer effectively prevents pitting and/or surface corrosion.

The surface corrosion mechanism then has an increased effect as a result of the high fissure rate.

Surface corrosion: Corrosive material loss is even.

In addition, high manganese-containing steels are prone to surface corrosion, which also limits the range of their applicability.

Formulations based on the invention claimed exhibit no surface corrosion in the condensation cycling test even after 10 cycles.

Figure 3a indicates general corrosion (with hydrogen evolution below potential A, and without hydrogen evolution above potential A).

In certain applications, this material undergoes localized corrosion problems (HIC for hydrogen induced cracking, stress corrosion due to H^S, SSCC for "sulfide stress corrosion cracking) and generalized corrosion, located throughout the

The immunity and general corrosion conditions are separated by a bold continuous line in these figures.

Figures 8a to 8d, which should be considered as provisional and subject to more or less major modifications, show immunity, generalized corrosion, pitting corrosion, imperfect passivity and perfect passivity areas in the presence of relatively concentrated chloride solutions (10­1molar, i.e. 3.5 g of CI per litre) for iron, chromium steel AISI 410, chromium­nickel steel AISI 304, and chromium­nickel­molybdenum steel AISI 316 respectively; their surfaces are polished with emery paper and electrolytically polished.

However, steels with higher manganese contents have a propensity of pitting and surface corrosion and without the addition of aluminum and/or silicone have a lower resistance against hydrogen-induced stress corrosion.

Typical material erosion for such surface corrosion lies in the range of from 100 to 150 ?m per year.

In terms of the surface corrosion, it is particularly important for the pipe walls in contact with the medium to have a uniform thickness, since locally thinner-walled points would otherwise lead to premature rusting through and therefore to leakage.

Since cutting elements often have substantially smaller thicknesses than the walls of the fitting or the pipe, surface corrosion by the medium can particularly rapidly lead to rusting through of the cutting element.

As a result of this corrosion, after disintegration of the coating the surface of the implant body is so fissured that intensified surface corrosion and also an increasing degree of crevice corrosion occur.

An acidic, low-oxygen medium which is many times more aggressive than the processes in surface corrosion is formed very quickly in the crevice.

We assess the depth and nature of the chemical load and of rust / corrosion (pitting, pit corundum, spongiosis, surface corrosion, etc.) on the basis of the ultrasonic wall thickness as an expert for the wall thickness measurement of steel, cast iron or plastic pipes for estimating the service life of the pipes.

In particular, this includes the work on surface corrosion of copper and the effectiveness of corrosion inhibitors to minimize copper release.

In a research project funded by the German Federal Ministry of Education and Research (BMBF) and the German Technical and Scientific Association on Gas and Water (DVGW) the chemical reactions during corrosion of copper pipes were studied.

The chromium, added as an alloying element, has two effects on the behaviour of steel in an acid environment : 1) it decreases the range of generalized corrosion area at low potentials, 2) it gives rise to a transpassive corrosion area at high potentials, with formation of hexavalent dissolved chromium.
