Ni 24.5Cr 6Al 0.4Y Powder Description:
Ni 24.5Cr 6Al 0.4Y Powder is a specialized thermal spray coating material renowned for its outstanding resistance to oxidation and hot corrosion. This alloy, when applied using atmospheric plasma spray (APS), offers effective protection against corrosion at temperatures up to 980°C (1800°F), and up to 1050°C (1920°F) when applied using HVOF or controlled atmosphere plasma spray methods (LPPS, LVPS, VPS). The presence of chromium and aluminum facilitates the formation of a protective oxide scale, crucial for extending the lifespan of high-temperature ceramic coating systems like thermal barrier coatings and ceramic abradable systems. Yttrium enhances the adhesion of this oxide layer, while alumina acts as an oxygen diffusion barrier, minimizing bond coat oxidation. This alloy's high chromium content is particularly beneficial for combating hot corrosion and sulfidation, making it a preferred choice for demanding industrial applications requiring robust performance under extreme thermal conditions.
