Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder Description:
Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder is a specialized thermal spray coating material designed for applications requiring exceptional resistance to high-temperature oxidation and hot corrosion. The presence of cobalt enhances coating ductility and hot corrosion resistance, while chromium and yttrium improve oxidation resistance by enhancing the activity of aluminum and the spallation resistance of the oxide scale. Chromium and aluminum act as reservoirs to replenish the oxide scale, crucial for maintaining coating integrity and avoiding embrittlement. The addition of tantalum further enhances oxidation resistance, making it ideal for overlay coatings on turbine engine components, ensuring prolonged performance and service life even under harsh operating conditions.
