High-temperature oxidation of nickel-based alloys and estimation of the adhesion strength of resulting oxide layers [PDF]
The kinetics of isothermal oxidation (1100°C) of commercial nickel-based alloys with different content of sulfur (0.22–3.2 wt ppm) is studied. The adhesion strength in a metal/oxide system is estimated as a function of sulfur content and duration of high-
