Corrosion engineering

Cathodic protection

Materials science; Corrosion engineering

(1) Reduction of corrosion rate by shifting the corrosion potential of the electrode toward a less oxidising potential by applying an external electromotive force. (2) Partial or complete protection ...

Chromizing

Materials science; Corrosion engineering

A surface treatment at elevated temperature, generally carried out in pack, vapor, or salt bath, in which an alloy is formed by the inward diffusion of chromium into the base metal.

High-temperature hydrogen attack

Materials science; Corrosion engineering

A loss of strength and ductility of . Steel by high-temperature reaction of absorbed hydrogen with carbides in the steel resulting in decarburization and internal fissuring.

Passivator

Materials science; Corrosion engineering

A type of inhibitor that appreciably changes the potential of u metal to a more noble (positive) value.

Base

Materials science; Corrosion engineering

A chemical substance that yields hydroxyl ions (OH) when dissolved in water. Compare with acid.

Deoxidizing

Materials science; Corrosion engineering

(1) The removal of oxygen from molten metals by use of suitable deoxidizers. (2) Sometimes refers to the removal of undesirable elements other than oxygen by the introduction of elements or ...
