Potentiostatic Study on the Anodic Behaviour of Iron-Chromium
• ferrous alloys: iron is the prime constituent • ferrous alloys are relatively inexpensive and extremely versatile • thus these alloys are wide spread engineering materials •alloys that are so brittle that forming by deformation is not possible ordinary are cast • alloys that are amenable to mechanical wrought.
Some alloys were synthe-sized, others were obtained commercially. Alloys which possessed good strength properties were emphasized for selection. The results indicate that the spark-shower radiance of plain carbon steels and carbon alloy steels was greater than for pure iron.

Applying forced convection was found to deplete iron from solidified aluminum, and evidence for the entrainment of iron within fluid flow streamlines was observed.
The oxide scales grown on the various alloys at 1373 k exhibited the presence of thick iron rich oxides in the scales. The presence of iron rich scales is described as a result of failure of the chromia scale and subsequent breakaway oxidation of the alloy.
The alloys were oxidized at 973, 1173 and 1373 k in either air or a hydrogen/argon mixture. The oxide scales formed on the various alloys at 973 k consisted of thin chromia layers. The oxide scales grown on the alloys at 1173 k also consisted of a chromia layer.
