Chromium, aluminium and titanium effect on nickel corrosion resistance in sodium sulfate and chloride melts
Description
The purpose of the study is to determine corrosion resistance of binary nickel alloys, alloyed with aluminium, titanium and chromium, in sodium sulfate and chloride melts. The content of aluminium, titanium and chromium varied from 0 up to 13,2; 21.4 and 36%, respectively. It was estabslished that resistance against slulfide corrosion grows in chromium-alloyed nickel and deoreases in nickel alloyed with aluminium and titanium. Nickel-chronium solid solutions containing > 16 to 17% Cr are characterized by the maximal stability in sodium sulfide melt and Ni3Al and Ni3Ti intermetallics -by the minimal one. Alloying nickel with aluminium titanium (up to 6 to 8%) and chromium (up to 10 to 12%) increases its resistance aginst sodium chloride melt. Binary Ni-Al-, Ni-Ti- and ternary Ni-Al-Ti-alloys possess a lower corrosion resistance in sodium sulfate as compared to sodium chloride
