Nanolayer of gold is obtained by the method of physical vapour deposition as a thermal barrier on a nickel-base superalloy. The effect of this layer on the aluminizing process and the efficiency for hot-corrosion resistance is studied by comparing two sets of samples: the first set, which is contained of the gold layer, while the second set is aluminized without this layer. The aluminizing process is carried out for both sets, using the pack-cementation method at a temperature of 1000°C. The samples coated with nanogold show a different behaviour from those samples, which are aluminized only, where the use of nanogold oxide improves the alloy ability to withstand hot-corrosion conditions.

KEY WORDS: diffusion coating, hot corrosion, nanogold, pack cementation, surface engineering
