Steady-state field evaporation of tungsten at high temperatures (T ~ 2000 K) has been studied using a magnetic mass spectrometer equipped with the field ion source. Only low-charged ions (W+2 and W+) have been observed in the course of evaporation. The distribution of the ion currents by tungsten isotopes correspondents to standart isotopic ratio for natural tungsten. Some deviations from standart isotopic ratio were observed owing to fluctuations and unstable nature of evaporation process. O.L. Golubev, N.M. Blashenkov

Deterioration Mechanism

The deterioration of aero lubricating oil at high temperatures was accelerated by using a specific device simulating the operating conditions of engines, where the deterioration mechanism was obtained. Structures of the deteriorated lubricating oils were analyzed by gas chromatograph/mass spectrometer. From the results, it can be concluded that deterioration of aero lubricating oil at high temperatures was composed of thermal pyrolysis, oxidation, and polymerization, with the generation of a variety of products, such as alcohols, aldehydes, acids, and esters, which caused the deterioration of physicochemical properties of the aero lubricating oil.
