“…The high temperature oxidation and corrosion resistance of aluminide coating can be enhanced by adding many elements (Montero et al, 2013;Zhao and Zhou, 2014;Yang et al, 2016;Huang et al, 2020). The common methods for preparing aluminide coating are thermal spray, pack cementation, chemical vapor deposition, and hot-dipping (Hu et al, 2006;Zhang et al, 2012;Cheng et al, 2013;Shirvani et al, 2013;Xu et al, 2015;Sitek et al, 2016). Comparatively, the pack cementation process is simple and the cost is low, so it is suitable for specimens with higher requirements for bonding strength of the coating (Yuwen and Zhou, 2016;Yu et al, 2019).…”
