High Temperature Oxidation of Advanced High Strength Steel: HT-XRD Method for Quantitative Evaluation
Thermal barrier coating (TBC) is a need for automotive components to avoid high temperature oxidation during hot forming. The formation of thick and flaky iron (Fe) oxide layers at high temperature on the high strength steel (HSS) is not acceptable because that can damage & pollute the pressing tool surface and interfere with the welding process. A TBC is evaluated on the HSS using HT-XRD (high temperature x-ray diffraction) technique to understand quantitative evolution of oxidation at high temperature. The characterisation results of the present coating system have shown significant reduction in oxidation of the substrate and inhibit the formation of flaky oxide layers at elevated temperature.
