Abstract

Chemical composition and some field electron and ion emission characteristics of thermo-field formations of two alloys Ir-Rh (60% Rh) and W-Hf (3% Hf) have been studied by time of flight atom probe. A remarkable segregation of Rh on the surface of Ir-Rh alloy have been proved at different cases. Such parameters as field evaporation fields have been determined. Field electron emission of some thermo-field formation on Ir-Rh alloy has been investigated. High temperature field evaporation has been studied for the W-Hf alloy and some enrichment of evaporating flow by Hf is supposed
