  • The stability of cast alloys and CVD coatings in a simulated biomass-combustion atmosphere
    Skobir Balantič, Danijela Anica ; Spiegel, Michael
    The corrosion resistance in a biomass-combustion environment was studied for the following materials: cast alloys (Alloy 800, Inconel 617, 1.4910, HCM 12 and P91), Fe-9 % Cr model alloys with and ... without additions of Al, Si and Mo, and cast alloys coated using the pack-cementation process with Al and Al-Si. The simulated atmosphere for the biomass-combustion environment contained 200g/g HCl, volume fractions 13 % CO[sub]2, 22 % H[sub]{2}O and 5 % O[sub]2. The samples were covered with a salt mixture of mass fractions of 52.4 % KCl and 47.6 % K[sub]{2}SO[sub]{4} in order to simulate the corrosion beneath the deposits. The specimens were exposed for 1000 h at the test temperature of 550 °C.
