چکیده
Hot corrosion is a critical problem in wide range of high-temperature applications. Ni–20Cr alloy frequently used such applications owing to its good hot-corrosion resistance. In the current work, thick plates thickness 6–10 mm were fabricated using cold spray-based additive manufacturing (CSAM). High-pressure spraying was with nitrogen as propellant gas. Pre- (substrate heating, SH) and post-heat treatments (hot isostatic pressing, HIP) also performed comprehend changes deposit properties. The deposits subjected microstructural mechanical characterization explore potential for CSAM standalone products. cold-sprayed successfully developed without any oxide formation. HIP treatment found be useful reduce porosity. substrate-heated exhibited excellent oxidation resistance at high temperature 900 °C.

High-temperature erosion-oxidation behavior of nickel-based alloys containing 0-7 wt.% Mo in fluidized bed waste incineration conditions was studied. A stream of hot condensed air with a flow rate of 25 L/min caused hot silica sand (700 °C) mixed with 0.5 wt.% of chloride salts to hit the specimens for 250 h. By removing the erosive factor, the high-temperature oxidation behavior of the alloys ...

In this study, the effect of surface morphologies on the isothermal oxidation behavior of MCrAlY coatings fabricated by high-velocity oxyfuel (HVOF) processes was investigated. To do so, free standing coatings with as-sprayed and polished surfaces were isothermally oxidized at 1050°C. The thickness of the bond coat was approximately 380μm. The Ra of the as-sprayed and polished surfaces were 6.4...
