The 70% NiCrAlY + 30% TiO 2 and 70% NiCrAlY + 25% Cr 2 O 3  + 5% YSZ metallic coatings are sprayed on titanium-15 alloy of ASTM B338, Grade 2, by using the plasma spray coating technology. Cyclic oxidation studies are conducted on the uncoated and coated alloys at 700 °C under static air environment...
