The effect of microstructure on the efficiency shielding or shunting magnetic flux by permalloy shields was investigated in present work. For this purpose, FeNi coatings with different grain structures were obtained using stationary and pulsed electrodeposition. coatings’ composition, crystal structure, surface microstructure, domain studied. It has been shown that 0.2–0.6 µm grains have a diso...

Abstract As an additional part of the artillery barrel, thermal sleeve is a cladding made insulation or conductive material mounted on outer surface which can greatly reduce bending deformation caused by sunlight exposure thus improving shooting accuracy artillery. In this paper, new type diamond barrel protection efficiency tested and analyzed, after testing, be as high 71.6%, much higher than...

This paper continues the analytical literature review on the theory and practice of metal protection by volatile corrosion inhibitors (VCI) supplemented by our own data. The principles and methods for fast estimation of VCI efficiency are reviewed.
