... inadvertently used on bolts for clamps used to join ducts that carried hot (500 °C, or 930 °F) air from the compressor of a military jet engine. (a) The nuts were fragmented or severely cracked. (b) The fracture surfaces of the nuts were oxidized and tarnished; purple, blue, and golden-yellow colors were...

... by uniform corrosion in some environments; the rusting of steel and the tarnishing of silver are typical examples of uniform corrosion. In some metals, such as steel, uniform corrosion produces a somewhat rough surface by the oxidation/reduction reaction, in which the end product (oxide) either dissolves...

... of tensile stress is related to the rupture of protective films during both initiation and propagation of cracks. These films may be tarnish films, such as those on brasses; thin oxide/hydroxide films; films richer in the more noble element of an alloy, such as a copper-gold alloy; or other protective films...

... of cracks. These films may be tarnish films, such as those on brasses; thin oxide films; layers richer in the more noble element of a binary alloy, such as a copper-gold alloy; or other passive films. Breaks in the passive film or enriched layer at various points on the surface initiate plastic deformation...
