The coating formation by Fe-Cr-Si codeposition was done in a single step via Halide Activated Pack Cementation (HAPC) on Nb-Si alloy with the aim of improving the oxidation resistance. The activator salt and temperature selections for HAPC process were obtained by thermodynamic analysis. The isothermal oxidation test results for the coated alloy at 1200 °C for 62 h showed good oxidation resistance. The mass gain was 17.5 mg/cm 2 . Furthermore, no cracks and spallation on the oxide layers weredoi:10.1590/1980-5373-mr-2020-0105 fatcat:mqyfpgknrzc65msfpfjlh4kxwu
