| Abstract: | Thermal analysis, thanks to its versatility, has been employed as an important testing approach for material science. Herein some special oxidation and corrosion thermogravimetry experiment of metallic sample were presented to show the advantage of hanging down system and a dedicated thermobalance. The optimization of experiment parameters and the further application of TG testing were also discussed. |
