Among coatings of NiCrAlY, CoCrAlY, and NiCoCrAlY the thermal fatigue resistance is highest for coatings of the NiCoCrAlY type under conditions of 100⇌950 °, th=1.5 min, Δɛ= 0.6-3.0%.

The resistance to thermal fatigue of heat-resistant, cast nickel alloy ZhS6U, directionally solidified, was determined.
