Corrosion behavior of Hf0.5Nb0.5Ta0.5Ti1.5Zr refractory high-entropy in aqueous chloride solutions
TL;DR: In this article, a refractory high-entropy alloy with excellent corrosion resistance in the 3.5 wt% NaCl solution is identified, which exhibits much better general corrosion resistance than that of 316L stainless steel, due to its corrosion current density being about one fifth of that in the latter.

Understanding the effectiveness of cathodic protection under disbonded coatings
TL;DR: In this paper, the effect of crevice gap size, solution conductivity and applied CP potential on the distribution and evolution of cathodic currents over the electrode array surface was investigated using a partially covered two dimensional electrode array that simulates a crevice under a disbonded coating and allows for the mapping of electrochemical currents under the influence of CP.
