Abstract
The study of oxidation kinetics and material behavior at high temperature is inevitable to choose a suitable candidate material for strategic applications. Co-based alloys are predominantly used in aerospace industries because of their excellent thermo-mechanical properties. We propose in-situ high temperature oxidation study to understand the microstructural and oxidation behavior of KC20WN alloy (Co-based) under hasty heating to static high temperature conditions. The oxidation behavior of alloys was measured with the help of biologic potentiostat/galvanostat workstation (two cell electrode system) attached with the high temperature furnace. The alloy samples were heated at different time (200 s to 10000 s) and temperature (800 °C and 1000 °C) in inside the furnace and their simultaneous oxidation/microstructural response was recorded using frequency response analyzer (FRA). In situ oxidation behavior was analyzed by charge transfer resistance (Rct) using EC-LAB software. Further, the oxidized samples were characterized using X-ray diffraction (XRD), optical microscopy, field emission scanning electron microscope (FESEM) and micro hardness tester.
