Preparation and Testing of Corrosion- and Spatiation- Resistant Coatings


Performer: University of North Dakota

Project No: FE0007325


Accomplishments


  • All materials, equipment, and clamps assembled for preparation of bonded parts.
  • Analysis of the diffusion rates of zinc through the three alloys has been completed at 700 and 1214oC.
  • At 700oC, the diffusivity in APMT is slightly higher (~4 vs. ~2 μm2/min) than in CM247LC.
  • The diffusion rate in the Rene 80 at 700oC was below UND detection limits.
  • The diffusion rate in APMT is approximately 20 times higher than in CM247LC or Rene 80 (~120 vs. ~8 μm2/min) at 1214oC.
  • The ANSYS finite element model of the clamping system has been completed, including the measured expansion data for the alloys. It is shown in Figure 1.
  • A sample calculated stress distribution in APMT at 1214oC using the present clamping system is shown in Figure 2.
  • Sampling of vapor and particulate matter present in filtered syngas created in pilot-scale gasification systems continues.
  • The particles collected after the system warm-gas filter are typically 0.2 to 0.5 μm in diameter, as shown in Figure 3.
  • After the syngas is combusted, the particles appear slightly larger and much more spherical, as shown in Figure 4.
