The typical coating process includes electroplating of 5–10 μm platinum followed by diffu-
sion aluminizing in low- or high-activity processes (Zhao and Xiao 2008). The microstructure of
platinum-modied coating can have a few characteristic structure types, due to platinum amount
and process type. In a single-phase structure, platinum dissolves in a solid solution, creating (Ni, Pt)
Al. In double-phase coatings, the PtAl

phase separation on a NiAl phase base is created. It can be
observed in the form of many separations, which can form even a continuous zone. The fundamen-
tal disadvantage of double-phase ...
