The transient oxidation of alloys | SpringerLink

The pre-steady-state oxidation of a wide range of binary alloys of practical importance, in 1 atm oxygen at 600° C, is discussed in terms of the main determining parameters, namely the free energies of formation and growth rates of the component and complex oxides, the bulk alloy composition, the alloy interdiffusion coefficient, the oxygen solubility and diffusivity in the alloy, and effects

Transition Metal Chemistry | Robert Gillard Part 1

[Co(NH 3) 5 (NO 2)] 2+ is not aquated directly in an acetate buffer, but it does react to give cobalt in the +2 oxidation state (90–92). This presumably results from initial electron transfer to the cobalt; the electron probably comes from the anion rather than from the ionic ligands, as in base hydrolysis, or thermal decomposition of [Co(NH 3 ) 6 ] 3+ and [Co(NH 3 ) 5 X] 2+ salts ( 93 ).
