Corrosion engineering

dichromate treatment

Materials science; Corrosion engineering

A chromate conversion coating produced on magnesium alloys in a boiling solution of sodium dichromate.

dimple rupture

Materials science; Corrosion engineering

A fractographic term describing ductile fracture that occurs through the formation and coalescence of microvoids along the fracture path. The fracture surface of such a ductile fracture appears ...

(1) A reduction of the anodic reaction rate of an electrode involved in corrosion. (2) The process in metal corrosion by which metals become passive. (3) The changing of a chemically active surface ...

ozone

Materials science; Corrosion engineering

A powerfully oxidizing allotropic form of the element oxygen. The ozone molecule contains three atoms (O 3 ). Ozone gas is decidedly blue, and both liquid and solid ozone are an opaque blue-black ...

stress-corrosion cracking (SCC)

Materials science; Corrosion engineering

A cracking process that requires the simultaneous action of a corrodent and sustained tensile stress. This excludes corrosion-reduced sections that fail by fast fracture. It also excludes ...

passivity

Materials science; Corrosion engineering

A condition in which a piece of metal, because of an impervious covering of oxide or other compound, has a potential much more positive than that at the metal in the active state.
