Abstract. The galvanic corrosion behavior of Cu-Ni Alloy(B10)/high strength steel (921A) has been studied using a zero-resistance ammeter (ZRA) in seawater at different temperatures. As well as it was systemically investigated by weight loss measurements, electrochemical methods and scanning electron microscope.Results showed 921A acts as the anode and B10 act as the cathodes. The effect of temperature on the galvanic corrosion is important, the corrosion rate became higher with the temperature increased.
Precision guided weapons (PGWs) have valuable application in field warfare. In order to interfere with Laser, Thermal Infrared (TIR) and Television guidance, this paper intends to research and develop a smoke-generating material that is capable of shielding visible lights, TIR and Millimeter Wave (MMW), based on the attenuation characteristic of expandable graphite to IR and MMW. The formulation is studied by orthogonal design, camouflage effect is verified by experiment, and the material with multiband interfering capacity is preliminarily prepared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
