The problem of wear-resistant coatings quality
Engineering Education # 02, February 2014 DOI: 10.7463/0214.0697616 The article aims at solving a problem concerning the express evaluation of the wear-resistant nanostructure coatings quality using the method of ultra-fluid jet examination. Conducted research activities have shown that an intensity of the coating delamination from the substrate depends on the stress concentration level in the test sample. The proposed informatively methodological procedure of ultra-fluid jet examination will allow prompt estimation of physical-and-mechanical parameters and operational condition of coatings being deposited on samples and passed fatigue loading. The offered procedure can be effectively used for selecting the coating material, substrate, and efficient modes of application.
Thermo-electrical motor for small and xsmall space vehicles
Engineering Education # 11, November 2012 DOI: 10.7463/1112.0492149 Nowadays small and minute space vehicles become more and more useful. It is possible to conduct a complex experiment, using such kind of satellites, at the same time launch of these satellites wouldn’t be too expensive. But deficiency of suitable motors makes usage of small satellites less effective. For solving this problem design of a compact thermo-electrical thruster for small space vehicles was developed and some results of laboratory experiments proving theoretical conclusions were published.
