... with oxidation or hot corrosion resistance, is required. In the present work, NiCrAlY and Ni - 20 Cr metallic coatings were deposited on an iron-based superalloy by a shrouded plasma spray process. The coatings were characterized by scanning electron microscopy, optical microscopy, microhardness testing, and x...
