Figure 4. Wetting behavior in Al/coating/Al2O3 system. (a-top) A comparison between Cr-42Si-9W monolithic substrate and Al2O3 substrate coated with thin films (~1.2 mm) of Cr-42Si-9W and the effect of coating materials (NiCoP, CoP, Ti, and Cr-42Si-9W) on wettability at (b-bottom) 953 K and (c-middle) 1,023 K.251
