Roles of Alloying Elements in the Corrosion Resistance of Equiatomic CoCrFeMnNi High-Entropy Alloy and Application to Corrosion-Resistant Alloy Design
نویسندگان
چکیده
The equiatomic CoCrFeMnNi alloy and the quaternary alloys with no addition of one element were fabricated, roles alloying elements in corrosion resistance clarified. In 1 M H2SO4, passivity was mainly due to Cr. Co Fe additions also contributed decrease current density. While Ni found suppress active dissolution, Mn increased dissolution rate. without indicated superior pitting 0.1 NaCl. To improve alloy, replaced Mo, effect Mo content on role assessed HCl.

Mitigation of Corrosion on Magnesium Alloy by Predesigned Surface Corrosion
Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...

Investigations were conducted on hot corrosion of Nickel base, NIMONIC-90 at 675°C and 725°C. The tests were carried out on small test coupons coated with a chemical containing Sodium sulphate and Sodium Vanadate which is representative of the corrosive deposit that usually forms during service in the coal fired boiler and the likes operating in marine atmospheres. Corrosion rates were measured...
متن کاملAlloy corrosion in a coal gasification system
The corrosion performance of alloys in coal gasification systems is of increasing industrial interest as more advanced coal-fired power generating systems are developed. It is necessary to consider the performance of candidate materials under likely exposure conditions to ensure that components have adequate lifetimes. Materials performance can influence the economic feasibility of these system...
