The Role of Alloying Elements on the Crevice Corrosion Behavior of Ni-Cr-Mo Alloys
The roles of the alloying elements Mo, Cr, and W in resisting crevice corrosion of UNS N06022, UNS N06625, and UNS N10362 have been studied under galvanostatic conditions in 5 mol/L NaCl at 150°C. Corrosion damage patterns were investigated using surface analytical techniques such as scanning electron microscopy and optical imaging, and the corrosion products characterized by energy dispersive ...
متن کاملEffect of Alloying Elements on Crevice Corrosion Inhibition of Nickel- Chromium-Molybdenum-Tungsten Alloys under Aggressive Conditions: An Electrochemical Study
The effects of Cr, Mo and W on the crevice corrosion of a number of commercial Ni-Cr-Mo (W) alloys in 1.0 mol/L NaCl were studied using the potentiodynamic-galvanostaticpotentiodynamic technique to measure film breakdown and repassivation potentials as well as protection temperatures. As expected, Cr is the key element determining resistance to crevice initiation but a substantial Mo alloy cont...
متن کاملEffect of Secondary Phase Precipitation on the Corrosion Behavior of Duplex Stainless Steels
Duplex stainless steels (DSSs) with austenitic and ferritic phases have been increasingly used for many industrial applications due to their good mechanical properties and corrosion resistance in acidic, caustic and marine environments. However, DSSs are susceptible to intergranular, pitting and stress corrosion in corrosive environments due to the formation of secondary phases. Such phases are...
متن کاملCorrosion Behavior of Stainless Steel Clad Rebar
Stainless steel clad rebar (SCR) was investigated because it may become a cost-effective means of controlling corrosion in concrete under very aggressive environments. Sound SCR (316L cladding) resisted corrosion in saturated Ca(OH)2 solution (SCS) with up to 5 wt% chloride. Cladding breaks on SCR induced significant corrosion of exposed underlying CS in SCS with only 1 wt% chloride. A computer...
متن کاملRoles of Alloying Elements on the Corrosion Behavior of Sputter-deposited Amorphous
Ternary amorphous W–xCr–yZr alloys containing 9−38 at % tungsten, 15−42 at % chromium and 39−73 at % zirconium were successfully prepared by direct current (DC) magnetron sputtering technique. The corrosion rates of all the examined sputter−deposited W–xCr–yZr alloys were in the range of 1 × 10−3 mm/y or lower which are nearly one order of magnitude lower than those of the sputter−deposited tun...
