OXIDATION MECHANISM OF NI-P ALLOYS

The powders of Ni-P alloys containing 13% of phosphorus were obtained by precipitation from the solution. The oxidation of Ni-P alloys in po lythermal conditions was studied. It was found that oxidation of Ni-P alloys goes through stages and that intermediate products of the oxida tion are: Ni2P and Ni2P2O7 The final products of oxidation process are NiO and Ni-3(PO4)(2). The sequence of chemical reactions describing t he oxidation of Ni-P alloys was proposed.
