NK5894 Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder

Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder Description:

Ni 23Co 20Cr 8.5Al 4Ta 0.6Y Powder is a specially formulated thermal spray coating material designed for applications requiring exceptional resistance to high-temperature oxidation and hot corrosion. The presence of Cobalt enhances the ductility of the coating and its hot corrosion resistance, while Chromium and Yttrium improve oxidation resistance by increasing the activity of Aluminium and the spallation resistance of the oxide layer. Chromium and Aluminium serve as a reservoir for replenishing the oxide layer, which is critical for maintaining the coating's integrity and preventing embrittlement. The addition of Tantalum further enhances oxidation resistance, making this coating ideal for overlay coatings on turbine engine components, thereby ensuring extended performance and lifespan even under harsh operating conditions.
