Abstract

The fatigue performance of a recently developed nickel superalloy disc was investigated at 700 °C in two environments: air and sulphur dioxide (SO2). Prior to testing, specimens were coated with various amounts of sodium sulphate (Na2SO4) and sodium chloride (NaCl) mixed salt (98% Na2SO4 + 2% NaCl),...
