Physicochemical investigation of NiAl with small molybdenum additions
Specimens of four cast NiAl alloys, three of them containing 0.5, 1.0 and 1.5 at. % Mo., were homogenized for 10, 10, and 140 hr at 1373, 1523 and 1273 K, respectively, then kept at 1073, 1173 and 1323 K for 60, 120 and 3 hr, respectively, and quenched in icy water. The precipitation of a metastable Ni3Mo phase was observed at temperatures between 1073 and 1523 K. Molybdenum substituted for nickel was found to inhibit the lattice disordering in NiAl at 1073 and 1523 K
Processes in spark electric discharge in air, nitrogen and oxygen
The yield of redox reactions in aqueous solutions under the action of a remote spark discharge in the air, nitrogen and oxygen was studied. Mohr's salt and potassium permanganate were used as test substances. The direct and indirect effects of a source of active particles were compared. On direct exposure active species can immediately interact with the substance. By indirect action the source of active species directly affects only water. Immediately after treatment water was mixed with a solution of the test substance and the reactions of accumulated active species with the test substance began. When discharged in air medium, the oxidation and reduction reaction yields are approximately the same 5 - 6 1(100 эВ)-1 eV. Equal yields means that active species are firstly produced in water. When discharged in the nitrogen and oxygen medium, the oxidation yield is ∼15% lower, and the recovery yield is much lower. In this case, there is oxygen or nitrogen in the aqueous solution, so nitrogen oxides cannot be formed in water. So the contribution of products, produced in the discharge region is not more than 15% and that radiation plays a major role in initiating of chemical processes in liquid. © Published under licence by IOP Publishing Ltd
Comparison of Mechanisms for the Action of Cold Electric Discharge Plasma and Hot Pulsed Discharge Plasma Emission on Water Solutions
Cold electric discharge plasma can be in direct contact with the water solution being treated. Active species are generated directly in the discharge and penetrate into the solution through the gas-liquid interface. Hot plasma of pulsed electric discharge can remotely affect an object without causing any thermal damage to it, e.g., by means of irradiating it. The effect of light penetrating into the solution is fundamentally different from the effect of cold plasma which is in contact with the solution: cold plasma already contains all active species, while radiation does not contain any of them. The species are generated in water solution when radiation passes through it. It is shown that the penetration depth of radiation into distilled water can be considerable. The method for activated water production based on the effect of plasma radiation can be more advantageous than that based on its treatment with cold plasma. © 2021 Institute of Physics Publishing.
