Abstract
To protect Nb–5Mo–15W alloy against high-temperature oxidation a novel coating was developed involving electroplating of a Re–Ni film, followed by pack cementation with Cr and Al. The coating consisted of a duplex-layer structure, an inner σ (Re–Cr) or Re(Cr) layer and an outer α Cr(Al) or β NiAl layer. The Re–Ni film containing more than 70 at.%Re, developed in the present investigation, is more useful than the conventional low Re–Ni film. The inner σ (Re–Cr) and Re(Cr) layer acts as a diffusion barrier between the Nb–5Mo–15W alloy substrate and the outer α-Cr(Al) or β-NiAl layer, which forms a protective α-Al2O3 scale. The coated Nb–5Mo–15W alloy was oxidized in air at 1373 K for up to 360 ks, showing very good oxidation resistance.
