Abstract
This work deals with the interaction between nickel-base superalloys a nd gaseous environments at high-temperatures. The oxidation acid nitri dation behaviour of the three singlecrystalline nickel-base superalloy s CMSX-6, CMSX-2, and SRR99 were investigated in air and oxygen-free n itrogen atmospheres at temperatures between 800 degrees C and 1200 deg rees C. The influence of mechanical deformation on the growth of oxide scales was studied on fatigued samples of the singlecrystalline nicke l-base superalloy CMSX-6.
