Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder Description:
Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder is a high-performance thermal spray coating material engineered for applications that demand superior resistance to high-temperature oxidation and hot corrosion. The cobalt content enhances the coating's ductility and resistance to hot corrosion, while the presence of chromium and yttrium boosts oxidation resistance by activating aluminum and improving the spallation resistance of the oxide scale. Both chromium and aluminum serve as reservoirs to replenish the oxide scale, which is essential for maintaining the coating's integrity and preventing embrittlement. Additionally, the inclusion of tantalum further strengthens oxidation resistance, making this powder ideal for overlay coatings on turbine engine components, ensuring extended performance and longevity even in demanding operating environments.
